A Remark on "A Non-Interacting Low Mass Blackhole-Giant Star Binary System": Companion Most Likely be a 'Triaxial Star'
Abstract: Thompson et al (2019) detected an unseen companion of the red-giant star 2MASS J05215658 +4359220 and interpreted this companion candidate as most likely a black hole. Reanalyzing the observational parameters van den Heuvel and Tauris (2020) concluded that the unseen companion might "not be a black hole "but it can be a close binary consisting of two main sequence stars of ~ 0.9 M?each. Further refining the observed data Thomas et al (2020) argued the nature of the companion in favor of black hole candidate. Based on numerical simulation's results and the detection super-luminous supernova ASASSN-15LH this author propose this unseen companion most likely be a 'Triaxial Quark Star' or simply a "Triaxial Star". The significant impacts are discussed.
