Available in PDF, EPUB and Kindle. Book excerpt: The final fates of stars and their planetary systems are in most cases embodied by white dwarfs. These are the compact remnants of stellar evolution for all low- to intermediate-mass stars in our Galaxy, including the Sun. The relative simplicity of white dwarfs makes them valuable tools in a variety of astrophysical contexts, from placing limits on the age of our Galaxy, to measuring the bulk abundances of exoplanets via the presence of actively accreted metals in their atmospheres. White dwarfs can also exhibit photometric variability for a variety of reasons, both as isolated stars and in binary systems, providing insights into white dwarf structure and circumstellar environments. In this dissertation we first present novel techniques to identify variable white dwarfs in modern time-domain photometric surveys. We then focus on identifying and characterizing two types of variable white dwarfs: those that pulsate and those being transited by circumstellar planetary debris. Using the unprecedented number of white dwarfs observed by Gaia and the Zwicky Transient Facility (ZTF), we define a set of variability metrics based on these publicly available catalogues to efficiently identify variable white dwarfs across the Gaia color magnitude diagram. We then present a dedicated search for pulsating He-atmosphere white dwarfs (DBVs) using McDonald Observatory follow-up observations, in an attempt to better define the observed extent of the helium-atmosphere white dwarf instability strip. We increase the number of DBVs from 28 to 47 using Sloan Digital Sky Survey spectroscopy to initially identify candidate DBVs. We find the observed blue and red edges of the DB instability strip are still hotter than theoretical expectations by about 1500K and 600K, respectively. Using our set of Gaia and ZTF variability metrics, we identify and characterize the second and third cases of white dwarfs with recurring planetary debris transits, with debris orbital periods differing by more than two orders of magnitude. These objects, in combination with the first known system, probe a unique parameter space constraining earlier stages of the planetary debris disruption and migration process

Download or read book Stellar Pulsations written by J.C. Suárez and published by Springer Science & Business Media. This book was released on 2012-10-20 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyses of photometric time series obtained from the MOST, CoRoT and Kepler space missions were presented at the 20th conference on Stellar Pulsations (Granada, September 2011). These results are leading to a re-appraisal of our views on stellar pulsation in some stars and posing some new and unexpected challenges. The very important and exciting role played by innovative ground-based observational techniques, such as interferometric measurements of giant pulsating stars and high-resolution spectroscopy in the near infrared, is also discussed. These Proceedings are distinguished by the format of the conference, which brings together a variety of related but different topics not found in other meetings of this nature.

Book Synopsis The Fourth Source by : Robert J. Tuttle
Download or read book The Fourth Source written by Robert J. Tuttle and published by Universal-Publishers. This book was released on 2012 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how the effects of nature's own nuclear reactors have shaped the Earth, the Solar System, the Universe, and the history of life as we know it. It focuses on observed effects that are poorly explained by our standard theories, identifies certain errors in those theories, and shows how these effects are caused by natural nuclear fission reactors. The theory of Plate Tectonics is wrong, and it is shown that expansion of the Earth causes continental drift. A physically reasonable mechanism is proposed for expansion and observational data are presented to show that this occurs. Evolution is explained as punctuated equilibrium, with mutations caused by abrupt surges of radiation, and related life forms that have been interpreted as seperate species are actually the result of radiation injury. This view is particularly effective as applied to humans. The ability of the dinosaurs to live so large is explained by use of Earth Expansion and a more massive atmosphere to provide buoyancy and effective transpiration of oxygen. These effects also explain how pterodactyls and ancient birds could fly. Expansion induced by impacts at the end of the Cretaceous caused the atmosphere to thin and the dinosaurs collapsed. Analysis of geological and biological data supports this. The astronomical distance scale is shown to be wrong, based on the misconception that trigonometric parallax is an absolute measurement. It isn't, and the method is led astray by the overwhelming number of asteroidal fragments masquerading as stars. The measurements of an expanding Universe are shown to be in error, and an expanding Universe is not needed by an alternative interpretation of Einstein's equations. This interpretation is based on the equal creation of matter and antimatter, which is known to occur. Spiral galaxies are not vast Island Universes of stars as we have thought, but are shown to be the strewn fields of debris from the nuclear fission detonation of distant planets.The Universe is not made up of 96% Dark Matter and Dark Energy, but is instead very ordinary. Abundant evidence and references provide support for all these interpretations. This book opens new opportunities for research by correcting several fundamental errors in our concepts of the Earth, Life, and the Universe.

Book Synopsis Exoplanets: Compositions, Mineralogy, Evolution by : Natalie R. Hinkel
Download or read book Exoplanets: Compositions, Mineralogy, Evolution written by Natalie R. Hinkel and published by Walter de Gruyter GmbH & Co KG. This book was released on 2024-09-02 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus for RiMG volume 90 is on rocky exoplanets because the search for truly Earth-like planets is of special interest. The goal is to motivate communication between the disciplines so as to make the best use possible of existing data and data yet to be collected by the James Webb and the Nancy Grace Roman Space Telescopes, since the astronomy community is gathering data on stars and exoplanets at an accelerating rate. Such data now include exoplanet size and mass (i.e., density) as well as their atmospheric compositions, which are collectively telltale of mineralogy and evolution. Much of what is published may still fall in the realm of educated speculation, but our conjectures are metamorphosing into testable hypotheses. There is now a remarkably large amount of astronomical data (with even more on the way) that geochemists and petrologists can make much use of. But just as astronomers may benefit from geologic insights, geologists need our colleagues in astronomy to help interpret their data and their underlying implications to better understand its astronomical context. Our hopes for this volume will be fulfilled if readers initiate their own analyses of what at present may seem like novel or unusual data, and if new collaborations between academic departments and subfields are forged.
