Numerical Study of Polytropes with n=1 and Differential Rotation
T. L. Razinkova, A. V. Yudin, S. I. Blinnikov
The solution space of differentially rotating polytropes with n=1 has been studied numerically. The existence of three different types of configurations: from spheroids to thick to…

Analytical approaches for rapid prediction of gravitational waveforms for relativistic binary systems
Aleksandra V. Mishakina, Sergei I. Blinnikov
We present a fast method for obtaining fully analytical approximations for gravitational waveforms produced by merging of neutron stars and/or black holes for the earliest stages o…

Opacity of Ejecta in Calculations of Supernova Light Curves
M. Sh. Potashov, S. I. Blinnikov, E. I. Sorokina
The plasma opacity in stars depends mainly on the local state of matter (the density, temperature, and chemical composition at the point of interest), but in supernova ejecta it al…
