HD 32239: An Algol type eclipsing binary with a y Doradus type component

HD 32239 is an Algol-type eclipsing binary with one of the components showing y Doradus type pulsation. In this study by using the Transiting Exoplanet Survey Satellite (TESS) observations of the HD 32239 system published in Sectors 5 and 32, we obtained the minima times of the eclipsing system and calculated the new light elements by using the (O - C) technique, the out of eclipse variation related to the pulsation was analysed in the frequency domain and g-mode pulsations were detected at frequencies of 1.24-2.83 d-1. After removing the pulsational variation from the light curve we obtained the physical and geometrical parameters of the components by using the well known Wilson-Devinney code.We found that the primary component is a y Doradus type star. In this work the HD 32239 system has been analysed in detail for the first time and we obtained masses and radii of the primary and the secondary components as M1 = 1.335 +/- 0.004M AE, M2 = 1.057 +/- 0.004M AE and R1 = 1.319 +/- 0.001R AE, R2 = 1.057 +/- 0.001R AE, respectively.
