Scientific paper

Infrared light curves of the RS CVn-type binary TY Pyxidis (HD 77137) in J, H, and K have been obtained and nearly sinusoidal light variations outside eclipse have been detected, similar to those observed in other RS CVn systems. The period of these variations is approximately equal to the orbital period of the system and their amplitude decreases with increasing wavelength. Irregular light variations have also been observed. There is no conspicuous infrared excess attributable to circumstellar emission.
