Response to Comment on "A Non-Interacting Low-Mass Black Hole -- Giant Star Binary System"

Abstract

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 $3.3_{-0.7}^{+2.8}$ M${}_{\odot }$.
