Accretion Processes in Astrophysics
It has been more than fifty years since the first significant paper on accretion flows was written. In recent years, X-ray satellites capable of identifying accretion disks and radiation jets – indications that accretion has taken place – have significantly advanced our understanding of these phenomena. This volume presents a comprehensive and up-to-date introduction to the major theoretical and observational topics associated with accretion processes in astrophysics. Comprising lectures presented at the twenty-first Winter School of the Canary Islands Institute of Astrophysics, the text emphasizes the physical aspects of accretion, investigating how radiation jets are produced, how accretion power is divided between jets and radiated energy, the geometry of accretion flow, and the accretion processes of active galactic nuclei. Written by an international team of experienced scientists, chapters offers young researchers key analytical tools for supporting and carrying out the next generation of front-line research.
Ignacio González Martínez-País, Instituto de Astrofísica de Canarias, Tenerife
Ignacio González Martínez-País is Lecturer at the Astrophysics Department of La Laguna University and Staff Researcher at the Institúto de Astrofísica de Canarias. His main research interests include the study of compact binaries in which accretion takes place: cataclysmic variables (harbouring a white dwarf as the accreting object) and X-ray binaries (harbouring a neutron star or black hole). He has extensive experience teaching related subjects such as general physics, fluid mechanics, differential equations, astrophysical instrumentation, observational techniques and accretion processes.
Tariq Shahbaz, Instituto de Astrofísica de Canarias, Tenerife
Tariq Shahbaz is Staff Scientist at the Institúto de Astrofísica de Canarias, where his research focuses on the study of compact objects, such as neutron stars and black holes, and determining their masses by developing methods to model the observed lightcurves and spectra. His other research interests include high time resolution phenomena and X-ray binaries. He is a member of the International Astronomical Union.
Jorge Casares Velázquez, Instituto de Astrofísica de Canarias, Tenerife
Jorge Casares Velázquez is Staff Scientist at the Institúto de Astrofísica de Canarias. His research focuses on the study of galactic black holes, with emphasis on the determination of their dynamical masses. He has promoted novel strategies for deriving fundamental parameters in X-ray binaries by exploiting the reprocessing of X-rays into optical line radiation. His other research interests include the study of gamma-ray binaries, cataclysmic variables and millisecond pulsars. He is a member of the International Astronomical Union and the Spanish Astronomical Society.
