5D memberships and fundamental properties of the old open cluster NGC 6791 based on Gaia-DR2

This paper investigates reliable memberships and fundamental astrophysical properties of the old (∼8 Gyr) open cluster NGC 6791 using the astrometric and photometric data of the Gaia data release 2 ( Gaia -DR2). We identify 2536 likely cluster members (≥0.6) in a five-dimensional (5D) parameter spac...
