Amplitudes versus orbital periods measured in the TESS light curves. Doppler beaming amplitudes (from the 3E solution) are plotted in gold colour, while A_1E (that could be due to irradiation either Doppler beaming), are in purple. Four different mass functions (0.5, 1, 5 and 10 M_⊙) for two different effective temperatures (T_eff = 40 and 150 kK) have been overplotted to see the position of the stars according to their corresponding effective temperature.
