Scientific paper

Observational information including photometric data on T Sex are examined to characterize the periodicity and amplitude variations of the object. T Sex is shown to be multiperiodic with three periods of pulsation 3.080537, 8.167766, and 13.333605 c/d with amplitudes of 0.235, 0.028, and 0.015 mag. The investigation verifies the variation of T Sex's principal period and is used to explain the variation in the amplitude of the day vs night light curves.
