Beschreibung
The book discusses the theoretical path to decoding the information gathered from observations of old stellar systems. It focuses on old stellar systems because these are the fossil record of galaxy formation and provide invaluable information ont he evolution of cosmic structures and the universe as a whole. The aim is to present results obtained in the past few years for theoretical developments in low mass star research and in advances in our knowledge of the evolution of old stellar systems. A particularly representative case is the recent discovery of multiple stellar populations in galactic globular clusters that represents one of the hottest topics in stellar and galactic astrophysics and is discussed in detail.
Autorenporträt
Santi Cassisi received his degree in physics from the University of Pisa, Italy, in 1991. He then spent a year at the Astronomical Observatory of Meudon-Paris, France, followed by a PhD-fellowship at the University of L'Aquila, Italy, from 1995 to 1997. In 1998, he accepted a post as staff researcher at the Collurania-Teramo-Observatory, a research unit of INAF. He currently holds a position as associate professor at the same institution. Professor Cassisi's research focuses on theoretical stellar evolution and its application to the study of both galactic and extra-galactic stellar populations. He has authored about 210 scientific papers, 115 of them in peer-reviewed journals, and a monograph. Maurizio Salaris studied physics at the University of Rome 'La Sapienza', and then worked at the Collurania-Teramo-Observatory, Italy, the Institut d'Estudis Espacials de Catalunya in Barcelona, Spain, the Max Planck Institute for Astrophysics in Garching, Germany, and the Astrophysics Research Institute of the Liverpool John Moores University, UK, where he currently holds the post of Professor of Stellar Astrophysics. He has published about 150 papers in peer-reviewed journals and books, plus a monograph, co-authored by Santi Cassisi. Professor Salaris's scientific work focuses on theoretical stellar evolution, stellar population synthesis models, and the interpretation of photometric and spectroscopic observations of Galactic and extragalactic stellar populations.
