Unveiling Subarcsecond Multiplicity in the Pleiades with Gaia Multicolor Photometry
Dmitry Chulkov
Abstract:The list of 409 probable cluster members down to G = 15mag (m ≳ 0.5M
⊙) is compiled for the two degree radius of the Pleiades, based on astrometric data from Gaia DR3 and the PPMXL catalog, along with several radial velocity surveys, including APOGEE and LAMOST. This approach allows for the inclusion of binary stars with unreliable Gaia solutions, thereby eliminating associated bias. Thus, the often-neglected 14 sources with Gaia two-parameter solutions are included. The subsequent analysis o… Show more
