Ultraviolet spectroscopy reveals a hot and luminous companion to the Be star+black hole candidate MWC 656

Johanna Müller-Horn, Varsha Ramachandran, Kareem El-Badry +11

The Galactic Be star binary MWC 656 was long considered the only known Be star+black hole (BH) system, making it a critical benchmark for models of massive binary evolution and for…
