摘要：
Cross correlations between observed and synthetic spectra are used to discover yet another satellite of BM Ori with the following characteristics: effective temperature T-eff = 4000 K, radius R = 16R(circle dot), mass M = 1.8M(circle dot), spectral type K7 III, absolute bolometric stellar magnitude M-b = + 4(m).0, axial rotation velocity V sini = 85 km/s, and relative luminosity 0.005 near the V band.
