GRO J1655-40 is a binary star consisting of an evolved F-type primary star and a massive, unseen companion, which orbit each other once every 2.6 days in the constellation of Scorpius. Gas from the surface of the visible star is accreted onto the dark companion, which appears to be a stellar black hole with … See more • List of nearest black holes See more • "GRO J1655-40".

WebApr 27, 2016 · GRO J1655−40's companion star was first identified as an F3-6IV sub-giant (Orosz & Bailyn 1997 ). This identification was later confirmed and refined to F6IV (Foellmi et al. 2006 ), and a significant stellar contribution to the optical and near-IR domain is therefore expected.
