论文摘要

Van den Heuvel&Tauris认为,如果系统2Mass J05215658+4359220中的红色巨型明星的质量为1个太阳能质量(M $ _ \ odot $),那么它的看不见的伴侣可能是由两个0.9 M $ _ $ $ _ \ odot $ $组成的二元组成的,这是一个三重系统。我们认为,现有数据与质量$ 3.2^{+1.0} _ { - 1.0} $ M $ _ \ odot $的巨人最一致,这意味着一个黑洞伴侣$ 3.3^{+2.8} _ { - 0.7} $ _ \ odot $。

van den Heuvel & Tauris argue that if the red giant star in the system 2MASS J05215658+4359220 has a mass of 1 solar mass (M$_\odot$), then its unseen companion could be a binary composed of two 0.9 M$_\odot$ stars, making a triple system. We contend that the existing data are most consistent with a giant of mass $3.2^{+1.0}_{-1.0}$ M$_\odot$, implying a black hole companion of $3.3^{+2.8}_{-0.7}$ M$_\odot$.
