Download or read book Extreme Stars written by James B. Kaler and published by Cambridge University Press. This book was released on 2001-03-22 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 200 years, our knowledge of stars has expanded enormously. From seeing myriad dots of different brightnesses, we moved on to measure distances, temperatures, sizes, chemical compositions, even ages, finding stars that dwarf our Sun and are dwarfed by it, some in their youth, others ancient. First published in 2001, Extreme Stars describes the lives of stars from a fascinating perspective. It examines their amazing extremes and results in an engaging overview of stellar evolution, suitable for anyone interested in viewing or studying stars. Ten chapters, generously illustrated throughout, explain the natures of the brightest, the largest, the hottest, the youngest, and so on, ending with a selection of the strangest stars the Universe has to offer. Taken as a whole, the chapters show how stars develop and die and how each extreme turns into another under the inexorable twin forces of time and gravity.
Download or read book Luminous Stars in Nearby Galaxies written by Roberta M. Humphreys and published by MDPI. This book was released on 2020-12-10 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on the populations of luminous stars in nearby resolved galaxies have revealed a complex distribution in the luminosity–temperature plane (the HR diagram). The fundamentals of massive star evolution are mostly understood, but the roles of mass loss, episodic mass loss, rotation, and binarity are still in question. Moreover, the final stages of these stars of different masses and their possible relation to each other are not understood. The purpose of this volume is to provide a current review of the different populations of evolved massive stars. The emphasis is on massive stars in the Local Group, the Magellanic Clouds, and the nearby spirals M31 and M33.

Download or read book Evolution of Massive Stars written by D. Vanbeveren and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive stars occupy an exceptional place in general astrophysics. They trigger many if not all of the important processes in galactic evolution whereas due to their intrinsic brightness, they offer the (only until now) possibility to study the stellar content and stellar behaviour in distant galaxies. The last, say, 25 years, massive stars have been the subject of numerous meetings discussing the influence of massive stars on population synthesis, the number distribution of different types of massive stars, the LBV phenomenon, WR stars, X-ray binaries, stellar winds in massive stars, chemical pecularities in massive stars, supernova explosions of massive stars and the important SN1987A event, the influence of massive stars and chemical evolution of galaxies. It is clear that without a theory of stellar evolution, the study of these topics loses a lot of its significance. Massive star evolution therefore got a chance in these meetings, but rarely as a prime subject. The state of the art, the physical processes and the uncertainties in stellar evolution were barely touched. Even more, the influence of close binaries in all these massive star meetings slowly disappeared the last, say, 13 years without any scientific justification, although a significant fraction of stars occurs in close binaries with periods small enough so that both components will interact during their evolution. Denying the binaries or not discussing their influence on results and conclusions, makes the latter very uncertain or even completely unreliable.

Download or read book Nearly Normal Galaxies written by Sandra M. Faber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is sometimes said that astronomy is the crossroads of physics. In the same spirit, it can forcefully be argued that galaxies are the crossroads of astronomy. Internal pro ces ses within galaxies involve all of the fundamental components of astrophysics: stellar evolution, star formation, low-density astrophysics, dynamics, hydrodynamics, and high-energy astrophysics. Indeed, one can hardly name an observational datum in any wavelength range on any kind of celestial object that does not provide a useful clue to galaxy formation and evolution. Although internal processes in galaxies until recently occupied most of our attention, we now know that it is also vital to relate galaxies to their environment. How galaxies congregate in larger structures and are in turn influenced by them are crucial questions for galactic evolution. On a grander level we have also come to regard galaxies as the basic building blocks of the universe, the basic units whereby the large scale structure of the universe is apprehended and quantified. On a grander level still, we also believe strongly that galaxies are the direct descendents of early density irregularities in the Big Bang. Galaxy properties are now viewed as providing a crucial constraint on the physics of the Big Bang and a vital link between the macroscopic and microscopic structure of the universe.
Download or read book Philoponus On Aristotle Meteorology 1 1 3 written by Philoponus, and published by A&C Black. This book was released on 2014-04-22 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aristotle's Meteorology influenced generations of speculation about the earth sciences, ranging from atmospheric phenomena to earthquakes. The commentary of John Philoponus (6th century AD) on the opening three chapters of Meteorology is here translated for the first time into English by Dr Inna Kupreeva, building on the work of L.G. Westerink. Philoponus, who today is increasingly respected as a philosopher in his own right, here engages critically with Aristotle's views about the building-blocks of our world, its size and relationship to other heavenly bodies, and reception of warmth from the sun. The translation in this volume is accompanied by a detailed introduction, extensive commentary notes and a bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: The universe is an amazing declaration of the glory and power of God! Beautiful and breathtaking in its scale, the vast expanse of the universe is one that we struggle to study, understand, or even comprehend in terms of its purpose and size. Now take an incredible look at the mysteries and marvels of space in The New Astronomy Book! Discover the best ways to observe the heavens, along with up-to-date astronomical data and concepts Learn about the dynamics of planets, stars, galaxies, and models for the cosmology of the universe What we know and are still trying to discover about planets, moons, and comets within our own solar system. If you watch the stars at night, you will see how they change. This speaks to the enormity and intricacy of design in the universe. While the stars appear timeless, they instead reflect an all–powerful Creator who speaks of them in the Bible. Many ancient pagan cultures taught that the changing stars caused the seasons to change, but unlike these pagan teachings, the Book of Job gives credit to God for both changing stars and seasons (Job 38:31-33). When Job looked at Orion, he saw about what we see today, even though he may have lived as much as 4,000 years ago.

This book was released on 2012-12-06 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our view of our Galaxy has recently been undergoing an increasing divergence from the traditional standpoint. In this book ten authors discuss in eight chapters how the conceptions of the Milky Way have moved in new directions. Starting with the inner parsec and the Center of the Galaxy, the book gradually moves on to the bulge and its relation to the globular clusters and to the disk, of which the presence of a bar is argued. A new look on the HI distribution in the disk, a synthesis of molecular line surveys and the study of stellar populations are discussed in the last three chapters.

Download or read book Angular Momentum Evolution of Young Stars written by S Catalano and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports the Proceedings of the NATO Advanced Research Workshop on "An gular Momentum Evolution of Young Stars" held from 17 to 21 September 1990 at Noto, Italy. The workshop had its immediate origin in a discussion about the availability of stel lar rotation data, that took place in 1987 at Viana do Castelo Portugal during the NATO meeting, Formation and Evolution of Low Mass Stars. We recognized that nearly 20 years had passed since the last meeting on stellar rotation and that significant progress in the observation of rotation rates in low mass stars had been made. During the last 20 years, new efficient instrumentation (CCD and photon counting de tectors and echelle spectrographs) and new analysis techniques (profile Fourier analysis) have allowed us to measure rotational velocities as low as 1-2 km/s and to reach low mass stars in young clusters. Even with these advances, rotational velocities of low mass stars would have remained challenging to determine if all single, low mass stars later than GO had rotational velocities of order or less than 10 km/sec. Evidence that this is not always the case was first provided by the photometric variability data obtained by van Leeuwen and Alphenaar for K dwarfs in the Pleiades and more recently by the vsini measurements of low mass stars in several young clusters.
