CANDIDATE TRIPLE-STAR SYSTEM WITH ELLIPSOIDAL COMPONENTS DETECTED IN VULPECULA THROUGH TESS PHOTOMETRY

MaGiV-1 is a candidate triple ellipsoidal star system in Vulpecula at coordinates RA(J2000) 19 : 52 : 19.13 and DEC(J2000) +23 : 29 : 59.7 classified as ELL+ELL, number 2344411 in AAVSO VSX database. Through photometry from the TESS Space Telescope, two significant periods describing the orbital times of the components were identified using the Fourier transform. The analysis led to determining PA-BC = (4.269 � 0.213) d the orbital period of the A-BC pair, the primary component with the secondary component described by another pair, and PBC = (0.610 � 0.031) d the orbital period of the BC pair, the inner ellipsoidal system. However, it cannot be completely ruled out that the shorter period can be explained by pulsations of one of the two components (e.g. by the GDOR type).
