Title: | Astrometric star-cluster membership probability: application to the case of M 37 with Gaia EDR3 | Authors: | Griggio, M. BEDIN, Luigi |
Issue Date: | 2022 | Journal: | MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY | Number: | 511 | Issue: | 4 | First Page: | 4702 | Abstract: | In this work, starting from the well-accepted relations in literature, we introduce a new formalism to compute the astrometric membership probabilities for sources in star clusters, and we provide an application to the case of the open cluster M 37. The novelty of our approach is a refined - and magnitude-dependent - modelling of the parallax distribution of the field stars. We employ the here-derived list of members to estimate the cluster's mean systemic astrometric parameters, which are based on the most recent Gaia's catalogue (EDR3). | URI: | http://hdl.handle.net/20.500.12386/32989 | URL: | https://academic.oup.com/mnras/article/511/4/4702/6534275 http://arxiv.org/abs/2202.07942v2 |
