BX Tri

BX Tri is a short-period (P = 0.192637 d) eclipsing binary composed of a couple of M dwarfs. The secondary star is cooler (T = 3106 K), less massive (0.26 M_Sol) and smaller (0.29 R_Sol). A visual companion star (LDS 3372 B) lies 1.2 arcseconds away (71 AUs at 59 pc), it too an M dwarf (Perdelwitz et al. 2018).
