Comets that were ejected by giant planets to the Oort cloud during the formation and evolution of planetary systems may get back to the orbits in the vicinity of the Sun with a time lapse under the gravitational influence of the same planets. The eva

Some asteroids, comets, and planets (ACPs) are accelerated by giant planets and ejected from parent planetary systems with velocities of several kilometers per second. When leaving a disintegrating stellar cluster rather than only a parent star, ACPs

Stars located closely to supermassive black holes (SMBHs) can, under certain conditions, form close binary systems with the SMBHs, in which the star may fill the Roche lobe and intensive accretion of stellar matter onto the SMBH is possible. In this

We present a three-dimensional model of the evolution of the asteroid–cometary–planetary (ACP) component of the Solar System under the gravitational influence of Jupiter. We demonstrate the origin of the Kuiper belt of the Sun, the Oort cloud of

This paper presents a scenario of the evolution of OB associations and star clusters from formation to decay, in the process of which they turn into stellar streams moving in the disk and stellar “rings” around the galactic center. The scenario a

The results of numerical modeling of white dwarf mergers on massive parallel supercomputers using a AVX-512 technique are presented. A hydrodynamic model of white dwarfs closed by a star equation of state and supplemented by a Poisson equation for th

Central, or “circumnuclear,” stars of the Galaxy, known as S stars, are studied. These stars can be used to investigate the gravitational potential near the Galactic center, which hosts a supermassive black hole (SMBH), as well as to impose const

Under certain conditions, stars close to intermediate-mass black holes (IMBHs) can form close binary systems with these objects, in which the Roche lobe can be filled by the star and intense accretion of the star’s matter onto the IMBH is possible.
