Formation of a Possible Black-hole Ultracompact X-Ray Binary with the Shortest Orbital Period
In the bulge of M31, the Chandra observations discovered a possible black hole (BH) ultracompact X-ray binary (UCXB) Seq.1 with an orbital period of 7.7 minutes and a maximum X-ray luminosity ${L}_{{\rm{X}}}=1.0{9}_{-0.01}^{+0.02}\,\times 1{0}^{38}\,{\rm{erg}}\,{{\rm{s}}}^{-1}$ in the 0.5–8 keV band...
