Physics of Relativistic Objects in Compact Binaries: from Birth to Coalescence: 359 (Astrophysics and Space Science Library). This book provides a comprehensive, authoritative and timely review of the astrophysical approach to the investigation of gravity theories. Particular attention is paid to strong-field tests of general relativity and alternative theories of gravity, performed using collapsed objects (neutron stars, black holes and white dwarfs) in relativistic binaries as laboratories. #astronomy, astrophysics, astronomia, astrofísica
