The Complex Lives of Star Clusters

The Complex Lives of Star Clusters PDF Author: David Stevenson
Publisher: Springer
ISBN: 3319142348
Category : Science
Languages : en
Pages : 343
Book Description
As with the author’s recent books Extreme Explosions and Under a Crimson Sun, the complex topic of star clusters is broken down and made accessible with clear links to other areas of astronomy in a language which the non-specialist can easily read and enjoy. The full range of topics are addressed regarding how star clusters are formed. Why is it some are dense conglomerates of stars while others are looser associations? Are the young, brilliant clusters seen in neighboring galaxies such as the Large Magellanic Cloud, M33 or M82 analogous to the ancient globulars seen in the Milky Way? How will these clusters change as their stars wane and die? More interestingly, how does living in a dense star cluster affect the fates of the stars and any attendant planets that accompany them? Star clusters form many of the most dazzling objects in the astronomers’ catalogs. Many amateur astronomers are interested in exploring how these objects are created and what it would be like to live among these objects. From the historical views of how star clusters came about to the most recent assumptions about how stars within these clusters evolve, different strands of science, from observation to theory, are woven together into a compelling investigation specifically targeted at amateur astronomers.

The Nature of Life and Its Potential to Survive

The Nature of Life and Its Potential to Survive PDF Author: David S. Stevenson
Publisher: Springer
ISBN: 3319529110
Category : Science
Languages : en
Pages : 456
Book Description
This book looks at the persistence of life and how difficult it would be to annihilate life, especially a species as successful as humanity. The idea that life in general is fragile is challenged by the hardiness of microbes, which shows that astrobiology on exoplanets and other satellites must be robust and plentiful. Microbes have adapted to virtually every niche on the planet, from the deep, hot biosphere, to the frigid heights of the upper troposphere. Life, it seems, is almost indestructible. The chapters in this work examine the various scenarios that might lead to the extermination of life, and why they will almost always fail. Life's highly adaptive nature ensures that it will cling on no matter how difficult the circumstances. Scientists are increasingly probing and questioning life's true limits in, on and above the Earth, and how these limits could be pushed elsewhere in the universe. This investigation puts life in its true astronomical context, with the reader taken on a journey to illustrate life's potential and perseverance.

Red Dwarfs

Red Dwarfs PDF Author: David S. Stevenson
Publisher: Springer Nature
ISBN: 3030255506
Category : Science
Languages : en
Pages : 370
Book Description
This thought-provoking book looks at the nature of red dwarf systems as potential homes for life. Realistically, what are the prospects for life on these distant worlds? Could life evolve and survive there? How do these planetary surfaces and geologies evolve? How would life on a planet orbiting a red dwarf differ from life on Earth? And what are the implications for finding further habitable worlds in our galaxy? The author provides readers with insight into the habitability of planets and how this changes as time progresses and the central star evolves. Since the previous 2013 edition Under a Crimson Sun, there has been a rise in newly discovered planets orbiting red dwarfs, accompanied by controversial areas of research that test what we think we know about these systems. This revised edition delves into the wealth of new material uncovered since that date. It explains the often conflicting results and analyses put forward and clarifies our understanding of these exciting new worlds. The chapters explore the full width of relevant scientific discovery and speculation on the potential for red dwarf planets to host life. New content includes improved atmospheric models, new understandings of the impact of stellar radiation on the atmosphere of red dwarf worlds, tidal-locking, and comparisons with terrestrial geology and climate.

The Birth of Star Clusters

The Birth of Star Clusters PDF Author: Steven Stahler
Publisher: Springer
ISBN: 3319228013
Category : Science
Languages : en
Pages : 199
Book Description
All stars are born in groups. The origin of these groups has long been a key question in astronomy, one that interests researchers in star formation, the interstellar medium, and cosmology. This volume summarizes current progress in the field, and includes contributions from both theorists and observers. Star clusters appear with a wide range of properties, and are born in a variety of physical conditions. Yet the key question remains: How do diffuse clouds of gas condense into the collections of luminous objects we call stars? This book will benefit graduate students, newcomers to the field, and also experienced scientists seeking a convenient reference.

Star Clusters in the Era of Large Surveys

Star Clusters in the Era of Large Surveys PDF Author: André Moitinho
Publisher: Springer Science & Business Media
ISBN: 3642221130
Category : Science
Languages : en
Pages : 266
Book Description
The symposium “Star Clusters in the Era of Large Surveys” was held in Lisbon on Sep 9-10 during the JENAM 2010. It served as a platform for discussing what and how recent, on-going and planned large-area ground-based and space-based surveys can contribute to producing a major leap in this research field, which has a strong European history. Scientific topics addressed included: cluster searches, clustered vs. isolated star formation, large-scale star formation, enrichment of the field population, structure, populations and evolution of the Milky Way, cluster dynamics (internal and within the Milky Way), variability of stars in clusters (from time-resolved surveys), analysis techniques for large samples and archiving. This proceedings book provides a snapshot of the ongoing discussion on the role of large surveys in star cluster research, and serves as a reference volume for the state-of-the art in the field.

Dynamics of Young Star Clusters and Associations

Dynamics of Young Star Clusters and Associations PDF Author: Cathie Clarke
Publisher: Springer
ISBN: 3662472902
Category : Science
Languages : en
Pages : 348
Book Description
Where do most stars (and the planetary systems that surround them) in the Milky Way form? What determines whether a young star cluster remains bound (such as an open or globular cluster), or disperses to join the field stars in the disc of the Galaxy? These questions not only impact understanding of the origins of stars and planetary systems like our own (and the potential for life to emerge that they represent), but also galaxy formation and evolution, and ultimately the story of star formation over cosmic time in the Universe. This volume will help readers understand our current views concerning the answers to these questions as well as frame new questions that will be answered by the European Space Agency's Gaia satellite that was launched in late 2013. The book contains the elaborated notes of lectures given at the 42nd Saas-Fee Advanced Course “Dynamics of Young Star Clusters & Associations" by Cathie Clarke (University of Cambridge) who presents the theory of star formation and dynamical evolution of stellar systems, Robert Mathieu (University of Wisconsin) who discusses the kinematics of star clusters and associations, and I. Neill Reid (S pace Telescope Science Institute) who provides an overview of the stellar populations in the Milky Way and speculates on from whence came the Sun. As part of the Saas-Fee Advanced Course Series, the book offers an in-depth introduction to the field serving as a starting point for Ph.D. research and as a reference work for professional astrophysicists.

The Emergence of Personhood

The Emergence of Personhood PDF Author: Malcolm Jeeves
Publisher: Wm. B. Eerdmans Publishing
ISBN: 0802871925
Category : Philosophy
Languages : en
Pages : 246
Book Description
Despite the many well-documented similarities -- genetic, cognitive, behavioral, social -- between our human selves and our evolutionary forebears, a significant gulf remains between us and them. Why is that? How did it come about? And how did we come to be the way we are? In this book fourteen distinguished scholars -- including humanist, atheist, and theist voices -- address such questions as they explore how and when human personhood emerged. Representing various disciplines, the contributors all offer significant insights into new scientific research about the origins of human nature -- research that challenges some traditional views.

Star Trek: The Next Generation: Greater than the Sum PDF Author: Christopher L. Bennett
Publisher: Simon and Schuster
ISBN: 1416572163
Category : Fiction
Languages : en
Pages : 384
Book Description
The Starship Rhea has discovered a cluster of carbon planets that seems to be the source of the quantum energies rippling through a section of space. A landing party finds unusual life-forms inhabiting one of the planets. One officer, Lieutenant T'Ryssa Chen -- a half-Vulcan -- makes a tenuous connection with them. But before any progress can be made, the Rhea comes under attack from the Einstein -- a Starfleet vessel now controlled by the Borg. The landing party can only listen in horror as their comrades are assimilated. The Borg descend to the planet, and just as Chen accepts that she will be assimilated, the lieutenant is whisked two thousand light-years away. A quantum slipstream -- instantaneous transportation -- is controlled by these beings in the cluster, and in the heart of the cluster there is now a Borg ship. Cut off from the rest of the Borg collective, the Einstein cannot be allowed to rejoin it. For the sake of humanity, the Borg cannot gain access to quantum slipstream technology. Starfleet Command gives Captain Picard carte blanche: do whatever he must to help the beings in the cluster, and stop the Einstein no matter the cost.
