Circumsolar Stellar Streams and Meteors in the Earth Atmosphere

Abstract

On the basis of the Gaia data, we analyze the formation pattern of peripherical structures of planetary systems, the elements of which are dust, asteroids, comets, and unbound planets (the so-called ACP structures). These structures, "ACP spears," are as large as 30 to 10⁴ pc; and, intersecting one with another, they permeate the Galaxy disk space. Estimates of the number of these spears show that they span the disk volume multiple times (~10⁴). We present a map of the sky with indication of the positions of ACP spears of stars that are close to the Sun; the dust streams of these stars may be dense enough to be identified as meteor streams in the Earth's atmosphere. The other sources of interstellar meteors are the Milky Way and two Kapteyn streams of stars. It is supposed that some of the meteorites in the terrestrial collections are the products of evolution of planetary systems around the stars of the Galaxy.
