The mass of the black hole in the low-inclination LMXB transient system GRO J0422+32 (=Nova Persei 1992)
We present the first infrared light curve of GRO J0422+32, and use it along with R-band data and published I- and Cousins R_c-band data to constrain the inclination of the system to be between 10 deg and 26 deg, implying that the black hole mass is greater than ~15Msolar. Remodeling the data with a 30 per cent accretion disc contamination level
