Pulsations of the AS Cam Eclipsing Binary in TESS Light Curves

n analysis of TESS satellite observations of the AS Cam eclipsing binary has shown that the light of this source pulsates at two frequencies: ν_1 = 0.7556 days –1 and ν_2 = 0.8658 days –1 with the amplitudes A_1 = 0_.^m0110 and A_2 = 0_.^m0087, correspondingly. Such variations are typical for slowly pulsating B-type stars. We modeled the light curves of AS Cam obtained from 1968 to 2019 to confirm the discovery of a gradual increase in the orbit eccentricity of the system by approximately 0.018 over 50 years. A third light, as one of the light curve solution parameters, on average, amounts to approximately 4
