The Complex Lives of Star Clusters

Author: David Stevenson
Publisher: Springer
ISBN: 3319142348
Category : Science
Languages : en
Pages : 351

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.

Under a Crimson Sun

Author: David S. Stevenson
Publisher: Springer Science & Business Media
ISBN: 1461481333

Languages : en
Pages : 331

Book Description
Gliese 581 is a red dwarf star some 20.3 light years from Earth. Red dwarfs are among the most numerous stars in the galaxy, and they sport diverse planetary systems. At magnitude 10, Gliese 581 is visible to amateur observers but does not stand out. So what makes this star so important? It is that professional observers have confirmed that it has at least four planets orbiting it, and in 2009, Planet d was described in the letters of The Astrophysical Journal as “the first confirmed exoplanet that could support Earth-like life.” Under a Crimson Sun looks at the nature of red dwarf systems such as Gliese as potential homes for life. Realistically, what are prospects for life on these distant worlds? Could life evolve and survive there? How do these planetary surfaces and geology evolve? How would life on a red dwarf planet differ from life on Earth? And what are the implications for finding further habitable worlds in our galaxy? Stevenson provides readers with insight into the habitability of planets and how this changes as time progresses and the central star evolves. Explore with him in this engaging, fascinating book the possibilities for finding life, from bacteria to more complex and even intelligent organisms, on red dwarf system planets.

Languages : en
Pages : 376

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.

Hubble Legacy

ISBN: 1454936231
Category : Science
Languages : en
Pages : 372

Book Description
The definitive book on the Hubble Space Telescope, written by a noted astronomer, geologist, and planetary scientist. Looking deep into space, by definition, means looking back in time—and the Hubble Space Telescope can look very far back, including at stars, nebulae, and galaxies that are millions, even billions, of years old. If there is a single legacy of Hubble as it turns thirty years old and nears the end of its useful life, it is this: It has done more to chronicle the origin and evolution of the known universe than any other instrument ever created. Hubble has also captured an astounding collection of ultraviolet images that include geysers of solar light, Mars’ famous dust storms, exploding stars, solar flares, globular clusters, and actual galaxies colliding. As for scientific milestones, Hubble has helped us learn that the universe is 13.8 billion years old, that just about every large galaxy features a black hole at its center, and that it's possible to create 3-D maps of dark matter. Hubble Legacy will not only feature the most stunning imagery captured by the telescope, but also explain how Hubble has advanced our understanding of the universe and our very creation. Praise for Hubble Legacy “Along with his clear description of the Hubble Space Telescope’s setbacks and successes, Jim Bell has compiled an exquisite collection of stunning photographs of the universe. Have many long looks— your tax dollars at work— an astronomer’s catalog of the cosmos.” —Bill Nye, CEO, The Planetary Society “You can’t flip through this stunning collection of Hubble images without pausing often to shake your head in awe. The accompanying text that Contributing Editor Jim Bell wrote is equally enriching. Altogether, this coffee-table book is a riveting celebration of the venerable space telescope’s 30th anniversary.” —Sky & Telescope

The Nature of Life and Its Potential to Survive

Author: David S. Stevenson
Publisher: Springer
ISBN: 3319529110
Category : Science
Languages : en
Pages : 466

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.

Pages : 205

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.

Pages : 606

Book Description
Star clusters are important to many areas of astronomy, and as the basic building blocks of galaxies, they can be used as key diagnostic tools within a wide range of disciplines in astrophysics. Star cluster populations are powerful tracers of the formation, assembly and evolutionary history of their parent galaxies. Although their importance has been recognised for decades, only in recent years has this area seen a major investment in time and effort. IAU Symposium 266 consolidates the expertise of leading researchers from a variety of topical subfields in astrophysics, to provide a comprehensive presentation of cutting-edge developments in theory, observations and simulations of star clusters and star cluster systems across a range of sizes and epochs. This volume gives an account of this forefront research, answering fundamental questions that will improve our understanding of numerous related issues and show how this field will take its next major step forward.

Star Clusters in the Era of Large Surveys

Languages : en
Pages : 270

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.
