Book Synopsis Catalogue of Mean UBV Data on Stars by : Jean-Claude Mermilliod
Download or read book Catalogue of Mean UBV Data on Stars written by Jean-Claude Mermilliod and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 1390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This catalog contains data on the magnitudes of more than 100,000 stars in the Galaxy. For each star listed, the catalog gives the position, identification, and ultraviolet, blue and visual magnitude from photoelectric measurements. The measurements from which these mean values were computed were collected from observations published between 1953 and 1992. The volume includes more than 1400 references.
Book Synopsis Literature 1971, Part 2 by : S. Böhme
Download or read book Literature 1971, Part 2 written by S. Böhme and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 6 contains literature published in 1971 and received before March 15, 1972; some older liter ature which was received late and which is not recorded in earlier volumes is also included.

Book Synopsis Astronomy in India: A Historical Perspective by : Thanu Padmanabhan
Download or read book Astronomy in India: A Historical Perspective written by Thanu Padmanabhan and published by Springer Science & Business Media. This book was released on 2014-08-20 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: India has a strong and ancient tradition of astronomy, which seamlessly merges with the current activities in Astronomy and Astrophysics in the country. While the younger generation of astronomers and students are reasonably familiar with the current facilities and the astronomical research, they might not have an equally good knowledge of the rich history of Indian astronomy. This particular volume, brought out as a part of the Platinum Jubilee Celebrations of Indian National Science Academy, concentrates on selected aspects of historical development of Indian astronomy in the form of six invited chapters. Two of the chapters – by Balachandra Rao and M.S. Sriram – cover ancient astronomy and the development of calculus in the ancient Kerela text Yuktibhasa. The other four chapters by B.V. Sreekantan, Siraj Hasan, Govind Swarup and Jayant Narlikar deal with the contemporary history of Indian astronomy covering space astronomy, optical astronomy, radio astronomy and developments in relativistic astrophysics. These chapters, written by experts in the field, provide an in-depth study of the subject and make this volume quite unique.
Book Synopsis Expounding the Mathematical Seed. Vol. 1: The Translation by : Agathe Keller
Download or read book Expounding the Mathematical Seed. Vol. 1: The Translation written by Agathe Keller and published by Springer Science & Business Media. This book was released on 2006-06-22 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 5th century, the Indian mathematician Aryabhata wrote a small but famous work on astronomy in 118 verses called the Aryabhatiya. Its second chapter gives a summary of Hindu mathematics up to that point, and 200 years later, the Indian astronomer Bhaskara glossed that chapter. This volume is a literal English translation of Bhaskara’s commentary complete with an introduction.

Download or read book The Outer Galaxy written by Leo Blitz and published by Springer. This book was released on 1988 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes research into the fundamental properties of the outer Milky Way (including its mass, scale and rotation properties) and covers topics such as spiral structure, the interstellar medium, star formation, satellites of the Milky Way and the outer parts of some nearby galaxies. It contains new work on the outer rotation curve of the Milky Way, first results of a new low frequency galactic disk survey, new results on the scale of the Galaxy (the distance of the Sun from the center and the relation of the disk of the Milky Way to the halo). This is the first volume specifically dedicated to outer galaxy research. Professional astronomers and astrophysicists as well as graduate students will welcome this book as a guide in understanding the outer parts of the Milky Way and also other galaxies.

Book Synopsis Membership and Coronal Activity in the Ngc 2232 and Cr 140 Open Clusters by : National Aeronautics and Space Administration (NASA)
Download or read book Membership and Coronal Activity in the Ngc 2232 and Cr 140 Open Clusters written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-21 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Making use of eight archival ROSAT HRI images in the regions of the NGC 2232 and Cr 140, this project's primary focus is to identify X-ray sources and to extract net source counts for these sources in these two open clusters. These X-ray data would be combined with ground-based photometry and spectroscopy in order to identify G, K, and early-M type cluster members. Such membership data are important because, at present, no members later than spectral type approx. F5 are currently known for either cluster. With ages estimated to be approx. 25 Myr and at distances of just approx. 350 pc, the combined late-type membership of the NGC 2232 and Cr 140 clusters would yield an almost unique sample of solar-type stars in the post-T Tauri/pre-main sequence phase of evolution. These stars could be used to assess the level and dispersion of coronal activity levels, as a part of a probe of the importance of magnetic braking and the level of magnetic dynamo activity, for solar-type stars just before they reach the zero-age main sequence.
