Comment on "A noninteracting low-mass black hole-giant star binary system"

Ed P J van den Heuvel et al. Science. .

Abstract

Thompson et al (Reports, 1 November 2019, p. 637) interpreted the unseen companion of the red giant star 2MASS J05215658+4359220 as most likely a black hole. We argue that if the red giant's mass is ~1 solar mass, its companion can be a close binary consisting of two main-sequence stars. This would explain why no x-ray emission is detected from the system.
