Description
The authors report the first infrared light curve of GS 2000+25. By
modelling the brightness variations as ellipsoidal modulations of the
secondary star, the authors find the mass of the compact object to lie
between 4.8 and 14.4 Msun (90 per cent confidence) for
secondary masses ≤0.7 Msun; this result is independent of
the mass ratio, q. The upper inclination limit of the system is more
dependent on q, although the lower inclination limit is almost
independent of it, and for q = 20 the authors find the inclination of
the system to lie between 43° and 69°.
