Gravidynamics and quarks
Соколов В.В. «Гравидинамика и кварки». (In English).

URSS. 216 pp. (English). Cartoné. ISBN 978-5-396-00877-9.

The book presents the dynamic theory of gravitational interaction — gravidynamics, which agrees with modern theories of other fields, e.g. classical electrodynamics, quantum electrodynamics, quantum chromodynamics. Gravitational field is seen as consisting of two components — the tensor and the scalar ones. Given that, it is described what are the strong field's properties and the properties of extremely compact objects arising at the collapse — transition of matter to a new phase — quark-gluon plasma. It is shown how all the values of physical quantities calculated according to this theory totally agree with currently available observational data. The above strong field of a collapsar in gravidynamics, in which extremely compact objects with a bag of quark-gluon plasma with a radius of about 10km exist, could be an explanation of the observed mass distribution of compact objects in close binary stellar systems with a peak at about 6.7 solar masses.

The book is meant for astrophysicists, experts in gravitation, and students of physical disciplines.
