Structure of the open cluster Collinder 463 revealed by Gaia astrometry

In this work we present our new estimates of the fundamental parameters of the open cluster Collinder 463, based on Gaia astrometric and PanSTARRS photometric data. In addition to updating previously available parameter values we highlight the existence of an extended stellar “halo” which is closely...

Zusammenfassung:	In this work we present our new estimates of the fundamental parameters of the open cluster Collinder 463, based on Gaia astrometric and PanSTARRS photometric data. In addition to updating previously available parameter values we highlight the existence of an extended stellar “halo” which is closely related to the presently known star cluster.
