Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims to study the earliest heavily obscured phases of massive star formation in starburst (SB) galaxies through a multi-line analysis of the HC3N rotational transitions from the ground and vibrationally excited states (HC3N*). Due to its unique spectroscopic properties, we also discuss the potential of HC3N* as a tool to discern whether the obscured nuclei of galaxies are being heated by a SB or by an accreting super massive black hole (i.e. an active galactic nucleus; AGN). Star formation is one of the most relevant physical processes in the formation and evolution of a galaxy. In particular, the energy released back (feedback) to their surrounding interstellar medium (ISM) from massive stars profoundly impacts the galaxy’s evolution. In a SB galaxy, most star formation takes place in the nucleus and in the form of compact massive star clusters known as superstar clusters (SSCs), which represent one of the most extreme models of star formation. Another major source of energy that can profoundly impact the ISM of a galaxy is an AGN. Both massive star formation and the AGN can reduce the star formation efficiency of a galaxy and even halt future star formation through feedback mechanisms. Hence, to study the physical conditions of the gas driving the formation of SSCs and shed light on the formation of massive stars, which is still not well understood, we need to observe the earliest phases of massive star formation before significant feedback intervenes...
Book Synopsis The Formation and Evolution of Star Clusters by : Simon Goodwin
Download or read book The Formation and Evolution of Star Clusters written by Simon Goodwin and published by Imperial College Press. This book was released on 2013-09-01 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, our picture of star and cluster formation has changed hugely, we now believe that many — if not most — stars form in clusters, and the process of star and cluster formation is extremely rapid and dynamic. This book will provide an overview of our current understanding of the formation and evolution of star clusters. This book will cover our understanding of how gas turns into stars and the structure and kinematics of very young star forming regions. It will then describe how we think these young star forming regions evolve into clusters before destroying themselves. It will also cover our understanding of young clusters in external galaxies, especially starbursts, and how these populations could evolve into globular cluster systems.
Book Synopsis Not-So-Simple Stellar Populations in Star Clusters by : Chengyuan Li
Download or read book Not-So-Simple Stellar Populations in Star Clusters written by Chengyuan Li and published by Springer. This book was released on 2017-09-19 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on understanding the stellar populations of massive star clusters and aims to investigate the origin, evolution and properties of binary systems, their collision products, as well as the general characteristics (e.g. ages, metal content) of stellar population(s) in star clusters. It introduces the basic background knowledge of various stellar populations in star clusters as well as their formation, interaction and evolution and offers high impact observational results on our understanding of the formation and evolution mode of star clusters. Based on these discoveries, this book proposes a series of future projects that can shed light on these topics. The research introduced in this book reveals key features of star clusters formation and by extension how all stars formed in our universe.

Book Synopsis Star Clusters and How to Observe Them by : Mark Allison
Download or read book Star Clusters and How to Observe Them written by Mark Allison and published by Springer Science & Business Media. This book was released on 2006-04-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy enthusiasts will all appreciate the detailed yet easily-assimilated description of star clusters, how they were formed as our Milky Way galaxy, how they evolved, and how they are classified. The latest research has revealed a vast amount of fascinating information about the clusters, along with some spectacular photographs. Modern commercially-made telescopes enable amateur astronomers to see a surprising amount of detail, and to record – using CCD cameras, video, webcams or even film – some remarkably beautiful and detailed images. Contained here also is detailed information on using refractors, reflectors, and, of course, Meade and Celestron’s ubiquitous range of computer-controlled SCT telescopes.
Book Synopsis Super Star Cluster Formation, Effects, and Evolution in CO with ALMA by : Santina Michelle Consiglio
Download or read book Super Star Cluster Formation, Effects, and Evolution in CO with ALMA written by Santina Michelle Consiglio and published by . This book was released on 2018 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Super star clusters (SSCs) are important sources of energy, ionizing photons, and metals in galaxies. With masses of 100,000-1,000,000 M , SSCs have the mass necessary to create O and B stars as well as to form globular clusters. Despite their overall importance, little is known about how SSCs form, evolve, and affect their environments. In my thesis, I use submillimeter tracers of gas and its kinematics from the newly commissioned Atacama Large (Sub)Millimeter Array (ALMA) as well as the Submillimeter Array (SMA) to study SSCs, their associated gas and dust and feedback from young stars in two local dwarf galaxies, NGC 5253 and II Zw 40. In II Zw 40, we find a low gas-to-dust ratio (GTD) of ~70 in a cloud near a SSC, whereas we find GTD>270 in an isolated cloud with no associated star formation

Download or read book An Introduction to Star Formation written by Derek Ward-Thompson and published by Cambridge University Press. This book was released on 2011-02-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guiding the reader through all the stages that lead to the formation of a star such as our Sun, this advanced textbook provides students with a complete overview of star formation. It examines the underlying physical processes that govern the evolution from a molecular cloud core to a main-sequence star, and focuses on the formation of solar-mass stars. Each chapter combines theory and observation, helping readers to connect with and understand the theory behind star formation. Beginning with an explanation of the interstellar medium and molecular clouds as sites of star formation, subsequent chapters address the building of typical stars and the formation of high-mass stars, concluding with a discussion of the by-products and consequences of star formation. This is a unique, self-contained text with sufficient background information for self-study, and is ideal for students and professional researchers alike.
Book Synopsis The Physics of Star Formation and Early Stellar Evolution by : Charles J. Lada
Download or read book The Physics of Star Formation and Early Stellar Evolution written by Charles J. Lada and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 779 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of stars is one of the principle mysteries of nature. During the last two decades advances in technology have enabled more progress to be made in the quest to understand stellar origins than at any other time in history. The study of star formation has developed into one of the most important branches of mod ern astrophysical research. A large body of observational data and a considerable literat ure now exist concerning this topic and a 1arge community of international astronomers and physicists devote their efforts attempting to decipher the secrets of stellar birth. Yet, the young astronomerjphysicist or more advanced researcher desiring to obtain a basic background in this area of research must sift through a very diverse and sometimes bewildering literature. A literature which includes research in many discip1ines and sub discip1ines of classical astrophysics from stel lar structure to the interstellar medium and encompasses the entire range of the electromagnetic spectrum from radio to gamma rays. Often, the reward of a suc cessfu1 foray through the current literature is the realization that the results can be obsolete and outdated as soon as the ink is dry in the journal or the conference proceeding in which they are published.

Book Synopsis Astrophysics in the Next Decade by : Harley A. Thronson
Download or read book Astrophysics in the Next Decade written by Harley A. Thronson and published by Springer Science & Business Media. This book was released on 2009-02-03 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA’s James Webb Space Telescope (JWST), planned for operation in about five years, will have the capability to investigate – and answer – some of the most challenging questions in astronomy. Although motivated and designed to study the very early Universe, the performance of the observatory’s instruments over a very wide wavelength range will allow the world’s scientific community unequaled ability to study cosmic phenomena as diverse as small bodies in the Solar System and the formation of galaxies. As part of preparation to use JWST, a conference was held in Tucson, Arizona in 2007 that brought together astronomers from around the world to discuss the mission, other major facilities that will operate in the coming decade, and major scientific goals for them. This book is a compilation of those presentations by some of the leading researchers from all branches of astronomy. This book also includes a “pre-history” of JWST, describing the lengthy process and some of the key individuals that initiated early work on the concepts that would evolve to become the premier space observatory of the next decade.

Book Synopsis The Formation and Early Evolution of Stars by : Norbert S. Schulz
Download or read book The Formation and Early Evolution of Stars written by Norbert S. Schulz and published by Springer. This book was released on 2014-06-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Starburst regions in nearby and distant galaxies have a profound impact on our understanding of the early universe. This new, substantially updated and extended edition of Norbert Schulz’s unique book "From Dust to Stars" describes complex physical processes involved in the creation and early evolution of stars. It illustrates how these processes reveal themselves from radio wavelengths to high energy X-rays and gamma–rays, with special reference towards high energy signatures. Several sections devoted to key analysis techniques demonstrate how modern research in this field is pursued and new chapters are introduced on massive star formation, proto-planetary disks and observations of young exoplanets. Recent advances and contemporary research on the theory of star formation are explained, as are new observations, specifically from the three great observatories of the Spitzer Space Telescope, the Hubble Space Telescope and the Chandra X-Ray Observatory which all now operate at the same time and make high resolution space based observing in its prime. As indicated by the new title two new chapters have been included on proto-planetary disks and young exoplanets. Many more colour images illustrate attractive old and new topics that have evolved in recent years. The author gives updates in theory, fragmentation, dust, and circumstellar disks and emphasizes and strengthens the targeting of graduate students and young researchers, focusing more on computational approaches in this edition.

Download or read book Observing the Feedback from Embedded Super Star Clusters with NIRSPEC written by Daniel Parke Cohen and published by . This book was released on 2020 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the birth places of super star clusters (SSCs), starbursts provide a testbed of astrophysics on a vast range of scales, from the microphysics of star formation to the macrophysics describing the evolution of galaxies and ultimately the Universe as a whole. SSCs represent the dominant mode of star formation in the early Universe. In the local Universe, these ~1-10 Myr old systems host dense concentrations of thousands of massive stars, offering an unprecedented view of the likely progenitors of globular clusters. This dissertation investigates the influence of SSCs on the gas that they ionize and subsequent effect of their starbursts on the galaxies in which they form. In particular, I explore the following questions: how does massive star feedback clear natal gas from SSCs? What conditions allow a cluster to remain bound through this gas dispersal phase or form multiple generations of stars? Through what mechanisms do starbursts regulate the central mass evolution of disk galaxies? How do SSCs drive chemically enriched, galaxy-scale winds from starbursts? To study the launching of winds, we need tracers that can penetrate the dusty clouds around young SSCs, and both high spatial and spectral resolution. The Brackett line (4.05 m) is ideal, but not available to most observers. Using NIRSPEC (Keck II) we can map Br and probe the dynamics of heavily embedded HII regions near SSCs. In this thesis, we present NIRSPEC observations in a variety of starburst environments, with the aim of providing an empirical basis for the emerging paradigm in the formation of the most massive stellar systems.
