Constraints on the Evolution of an Overluminous Blue Supergiant from its Parent Open Cluster, vdBH 245

Constraints on the Evolution of an Overluminous Blue Supergiant from its Parent Open Cluster, vdBH 245

In this paper, we constrain the properties of an overluminous blue supergiant star (BSG) in the open cluster vdBH 245. We confirm the cluster membership of a sample of early-to-mid B-type stars using their proper motions, parallaxes, and radial velocities. We measure the stellar parameters through a...
