Photometric study of the Delta Scuti variable 2MASS J13122513+5443409 in UMa

Abstract

. We keep investigating the new variable of Delta Scuti type 2MASS J13122513+5443409 discovered by our group previously. We have analyzed the data obtained not only from the relatively small telescopes of Slovakia and Ukraine, but also from the TESS mission. We calculated the pulsation period and amplitude using the Lomb-Scargle periodogram. We found that the dominant period is about 0 . 079 days. However, the oscillations displayed beating, indicating the presence of several pulsation frequencies.
