The location of the moving group of the V1062C Corpion
Scientists from Germany and Hungary have fixed a new moving group of young stars. It is located in Upper Centaurus-Wolf (UCL) on the territory of the Association of Scorpio-Centauri. This association represents a cluster of massive young stars of spectral types O and B. It is located at a distance of 400 light years from us.
One of the subgroups is UCL, which is almost completely covered in areas of star birth. It was here that researchers noticed a new young moving group. She was named the V1062C Corpion. Found after analyzing the movement data from Gaia-TGAS, received at the end of 2016.
The V1062C Corpion is a cooperative group consisting of 63 young stars on the edge of the UCL section with a distance of 570 light years from Earth. Approved 12 members with radial velocities and parallaxes, 31 objects with parallaxes and radial velocities, and also 20 candidates. Despite their youth, the stars are not the same age. Age ranges from 4-25 million years. This difference can not yet be explained. The one-dimensional velocity dispersion reaches less than 1.0 km / s, and the mass varies from 0.7 to 2.6 solar.
Many stars in the group remain undetected. Scientists believe that the release of data Gaia-2 (expected in April 2018) will allow to find weaker members. Such objects will help to obtain important information about the process of star birth in associations.
