Computational Methods For Astrophysical Fluid Flow Vol. 199 : Saas-fee Advances Course 27. Lecture Notes, 1997 Swiss Society For Astrophysics And Astronomy
This book leads directly to the most modern numerical techniques for compressible fluid flow, with special consideration given to astrophysical applications. Emphasis is put on high-resolution shock-capturing finite-volume schemes based on Riemann solvers. The applications of such schemes, in particular the PPM method, are given and include large-scale simulations of supernova explosions by core collapse and thermonuclear burning and astrophysical jets. Parts two and three treat radiation hydrodynamics. The power of adaptive (moving) grids is demonstrated with a number of stellar-physical simulations showing very crispy shock-front structures.
High-performance charged-couple device (CCD) cameras have opened up an exciting new window on the Universe for amateur astronomers. This book provides a complete, self-contained guide to choosing and using CCD cameras. Beginning with a no-nonsense introduction to CCD cameras, the authors explain what determines camera performance and demonstrate how to use a CCD camera and accurately calibrate the images obtained. The book also presents a clear review of the software available for visualizing, analyzing and processing digital images. Finally, the authors navigate a series of key areas in astronomy where astronomers can make the best use of CCD cameras. This handy volume is packed with practical tips. It provides a clear introduction to CCD astronomy for novices and an indispensable reference for more experienced amateur astronomers.
