Abstract We have studied stellar candidates for close (within 1 pc) encounters with the Solar system. For all of the stars under consideration the kinematic characteristics have been taken from the Gaia EDR3 catalogue. The parameters of the encounters of these stars with the Solar system have been calculated using three methods: (1) the linear one, (2) by integrating the orbits in an axisymmetric potential, and (3) by integrating the orbits in a potential with a spiral density wave. All three… 

Star Clusters, Planets, Asteroids and Comets in the Light of Big Data

Planetary (exoplanetary) systems can lose comets, asteroids, and planets due to their host stars close approaches. Such encounters may occur during stars motion in the Galaxy disk. In this work, we

Analysis of Close Stellar Encounters with the Solar System

We consider 36 candidates for close (within 1 pc) encounters with the Solar system. These stars have been selected in accordance with the results of an analysis of their motion obtained by various
