RADIO LOOPS IN ZONE OF AVOIDING OF OPEN CLUSTERS

Abstract

New catalogues have confirmed the existence of open clusters avoiding zone in the Sun's vicinity. Originally the zone has been found out by Shatsova & Anisimova in 1990. The zone is filled with the radio loops I - IV, the loops opened later and HI areas. Probably the system of open clusters forms a spatial lattice of the density waves. Internal parts of the loops are inside its cells. Shells are limited by the crests of waves.
