Cygnus X-1 contains a 21-solar mass black hole -- implications for massive star winds

James C. A. Miller-Jones, Arash Bahramian, Jerome A. Orosz +23

The evolution of massive stars is influenced by the mass lost to stellar winds over their lifetimes. These winds limit the masses of the stellar remnants (such as black holes) that…
