Main Sequence + Compact Object binary candidates from Gaia eDR3 astrometric and spectroscopic excess noise
收藏资源简介:
Almost 3,000 candidate MS+CO systems selected from Gaia eDR3 via inferred periods and mass ratios derived from astrometric and spectroscopic errors. The sample is split into a bronze list (significant astrometric and spectroscopic RUWE, mass ratio > 1 and companion mass > 3 Msun). A subset of these is chosen as a silver list (propagating errors on mass ratio and companion mass to deselect systems which are not significantly above the previous criteria) Finally, a gold list is constructed from the subset of the silver list with non-significant spectroscopic RUWE - leaving 237 sources. We include the most relevant Gaia data for the system, as well as our inferred spectroscopic and photometric errors and RUWEs, and the inferred periods and mass ratios. Gaia's eDR3 source id, and the ra, dec position are included and thus other Gaia data, or data from other astronomical catalogs, can be found for these systems. The catalog and the underlying methods are explained in more detail in Andrews et al. 2022 (in prep.).
