A complete and comprehensive treatment of the physics of the stellar interior and the underlying fundamental processes and parameters. The text presents an overview of the models developed to explain the stability, dynamics and evolution of the stars, and great care is taken to detail the various stages in a star's life. The authors have succeeded in producing a unique text based on their own pioneering work in stellar modeling. Since its publication, this textbook has come to be considered a classic by both readers and teachers in astrophysics. This study edition is intended for students in astronomy and physics alike.

Evolution of Stars and Stellar Populations is a comprehensive presentation of the theory of stellar evolution and its application to the study of stellar populations in galaxies. Taking a unique approach to the subject, this self-contained text introduces first the theory of stellar evolution in a clear and accessible manner, with particular emphasis placed on explaining the evolution with time of observable stellar properties, such as luminosities and surface chemical abundances. This is followed by a detailed presentation and discussion of a broad range of related techniques, that are widely applied by researchers in the field to investigate the formation and evolution of galaxies. This book will be invaluable for undergraduates and graduate students in astronomy and astrophysics, and will also be of interest to researchers working in the field of Galactic, extragalactic astronomy and cosmology. * comprehensive presentation of stellar evolution theory * introduces the concept of stellar population and describes "stellar population synthesis" methods to study ages and star formation histories of star clusters and galaxies. * presents stellar evolution as a tool for investigating the evolution of galaxies and of the universe in general.

International smuggling has exploded, deepening and accelerating the collaboration of transnational organized crime and terrorist groups. Attacks like the Charlie Hebdo and Bataclan shootings in Paris, the kidnappings and murders by Boko Haram in Nigeria, and the San Bernardino shooting were partially funded by seemingly harmless illegal goods such as cheap cigarettes, smuggled oil, prostitution, fake Viagra, fake designer bags, and even bootleg DVDs. But how can this be? In Blood Profits, Vanessa Neumann, an expert on dismantling illicit trade, explains how purchasing illegal goods translates to supporting organized crime and terrorists. Neumann shows how the effects of the collapsed Iron Curtain, USSR scientists and intelligence agents left without work, regional trade pacts, the dissipation of the East-versus-West mentality, and new-age technology have all led to an intricate network of illegal trade. She leads the reader through a variety of cases, both by geography and by industry (selecting industries where illicit trade is generally poorly understood), before extracting lessons learned into some policy recommendations that we can all embrace.

IAU Symposium 263 provides a state-of-the-art review of icy bodies in the Solar System, a topic crucial to understanding processes involved in the Solar System's formation, the consequences for water on planets, and ultimately, the habitable zones around other stars. Ice-rich planetesimals which form beyond the snow line are discussed, using an interdisciplinary approach. The main topics covered include: accretion of icy grains in the protoplanetary disk, the long-period comet flux and the Oort cloud population, transfer mechanisms of bodies from their source regions to the Sun's neighborhood, the physics and dynamics of trans-Neptunian objects, transition objects (comets and asteroids), cryovolcanism and modeling the interiors of icy bodies, and a review of past, present and future space missions. This volume gives a broad overview of the importance of these bodies, from comets up to liquid water on terrestrial planets, and the formation of ices in the Solar System.

IAU Symposium 265 presents a unified picture of nucleosynthesis, the production of chemical elements over cosmic time. It explains how this chemical evolution links together the early Universe of the first stars, through the formation of galaxies and their diverse populations of stars, to a Universe of heavy-element rich stars and planets. The first generation of massive stars that drove reionization left their chemical signatures imprinted in the oldest low-mass stars, which we observe today. Chemical evolution is a broad, diverse and rapidly evolving field, due to the ever-expanding capabilities delivered by new arrays of instruments on large telescopes, together with significant advances in modelling and increasing access to large and accurate nuclear, atomic, and molecular databases. Written for researchers and graduate students, the topics covered in this volume provide a comprehensive overview of the scientific progress achieved in recent years.

The?rsteditionofthistextappearedin1994.Shortlyafterthethirdprinting, our editor suggested that we attempt a second edition because new devel- mentsinstellarstructureandevolutionhadmadeouroriginalworkoutdated. We (the original authors, CJH and SDK) reluctantly agreed but with res- vations due to the e?ort involved. Our initial reluctance disappeared when we were able to convince (cajole, twist the arm of, etc.) our new coauth- colleague Virginia Trimble to join us. (Welcome Virginia!) We (i.e., all three of us) hope that you agree that the present edition is a great improvement compared to the 1994 e?ort. Our objectives in this edition are the same ones we set forth in 1994: Whatyouwill?ndisatextdesignedforourtargetaudience:thety- cal senior undergraduate or beginning graduate student in astronomy or astrophysics who wishes an overview of stellar structure and e- lution with just enough detail to understand the general picture. She or he can go on from there to more specialized texts or directly to the research literature depending on talent and interests. To this end, this text presents the basic physical principles without chasing all the (interesting!) details. For those of you familiar with the ?rst edition, you will ?nd that some things have not been changed substantially (F = ma is still F = ma), while othersde?nitelyhave.Forexample,Chapter2hasbeencompletelyrewritten.

Two scientists give an enthusiastic, layperson's overview of a new supermaterial now in development that could transform many features of daily life, from creating new conveniences to improving health and safety. What if you discovered an infinitesimally thin material capable of conducting electricity, able to suspend millions of times its own weight, and yet porous enough to filter the murkiest water? And what if this incredible substance is created from the same element that fills the common pencil? That's graphene--a flat, two-dimensional, carbon-based molecule with a single sheet measuring only one atom thick. In this layperson's introduction to this revolutionary substance, a physicist and a chemist explain how graphene was developed, discuss the problems in scaling up production for large-scale commercial use, and forecast the potentially transformative effects of incorporating graphene into everyday life. Recent research developments include adding graphene to Silly Putty to make extremely sensitive and malleable medical sensors and compressing and fusing flakes of graphene to create a three-dimensional material that's ten times stronger than steel. This widely adaptable substance promises to change the way we interact with smartphones, laptops, information storage, and even condoms. It may also enable significant improvements to air purification, water filtration technologies, and drug delivery. This entertaining and widely accessible book offers a fascinating look into one of the most exciting developments in materials science in recent decades.
