论文摘要
汤普森等。 （报告，2019年11月1日，第637页，科学）解释了红色巨星2MASS J05215658+4359220的看不见的伴侣最有可能是黑洞。我们认为，如果红色巨人大约是一个太阳能，那么它的伴侣可能是由两个主序列恒星组成的近距离二元。这可以解释为什么从系统中未检测到X射线排放。
Thompson et al. (Reports, 1 November 2019, p. 637, Science) 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 is about one 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.
