Photometric analysis of RR Lyrae stars. II. T Sextantis. (1991). Revista Mexicana De Astronomía Y Astrofísica, 22(1), 275. https://astronomia.unam.mx/journals/rmxaa/article/view/1991rmxaa..22..275h

Abstract

An exhaustive study of all available observational data of T Sex has been made. A period analysis of photometric data of this star shows that it is multiperiodic with three frequencies of pulsation. The frequencies derived (3.080537, 8.167766 and 13.333605 c/d) with their corresponding amplitudes (0.235, 0.028 and 0.015 mag) fit observational data very closely covering a time span of 6.9 years explaining the variation in amplitude of its light curves from night to night. This analysis also supports a variation in its principal period.
