Discovery of a White Dwarf-Main Sequence Binary in Open Cluster NGC 752
arXiv:1808.05718
Abstract
We identify a likely member of the NGC 752 open cluster (based on Gaia DR2 proper motions and parallax) having photometry consistent with being a white dwarf and a relatively low-mass main sequence star. If confirmed, this would be the first white dwarf known in this nearby cluster, and the brightest.
