Abstract—Detailed calculations of elliptical light curves for X-ray novae in the quiescent state are presented
for three optical and infrared wavelengths: = 5500, 16 200, and 22 000 Å. Mass ratios q = M_X / M_V = 0.120
and effective temperatures for the optical star T = 3500–30 000 K are considered. The orbital inclination i is
varied over a wide range from 10 to 90. The results obtained can be used to determine the masses of relativ-
istic objects and the parameters of binary systems.
