Since binary pulsars represent a natural laboratory for testing relativistic field theories, it was interesting to study the problem of two bodies, in a strong field regime. Hence, this book is not only a complete review of the work done on binary pulsars but also, it includes an important step towards a more general solution to the problem of the strong field of two bodies; which is still far beyond the reach of researchers. This is done by modifying Curzon solution to describe the field of binaries. A more general formula for red-shift and Shapiro time delay were derived including additional…mehr

Produktbeschreibung
Since binary pulsars represent a natural laboratory for testing relativistic field theories, it was interesting to study the problem of two bodies, in a strong field regime. Hence, this book is not only a complete review of the work done on binary pulsars but also, it includes an important step towards a more general solution to the problem of the strong field of two bodies; which is still far beyond the reach of researchers. This is done by modifying Curzon solution to describe the field of binaries. A more general formula for red-shift and Shapiro time delay were derived including additional terms. Also, energy localization and the possibility of gravitational waves emission have been discussed. This book is a good reference for the relativists and astrophysicists. "The book presents a competent and reasonably complete summary of techniques developed for study of binary stars. It summarizes work that has been done on the relativistic two-body problem. The author traces the progressively more accurate models, and reviews what has been learned from detailed timing observations"..........Prof. J.H. Taylor (Nobel laureate in Physics 1993 for the discovery of the first binary pulsar)
