ID: NGC 1850 BH1

Status: Candidate

COMMENTS: Proposed as a BH+main sequence star by Saracino et al. 2022. El-Badry & Burdge (2022) proposed a stripped envelope star alternative, lowering the unseen companion mass. Saracino et al. 2023 revised radial velocity, increasing unseen mass again.

Be sure to sort these by score to see the papers which discuss this object the most. Also, if there are no references here, it is likely that the code which calls Simbad messed up, and I advise you go and check the references yourself.
