Frequency analysis of Gamma Doradus variables observed by TESS
We present a frequency analysis of $\gamma$ Dor variables based on the TESS photometric data: among 35 objects, period spacing patterns were found in five stars TIC 235680293, TIC 235682463, TIC 416401558, TIC 232620739 and TIC 406927322. We estimate their near-core rotation and make an assumption about the pulsation modes. Also three objects TIC 75784209, TIC 318837103, and TIC 309662501 show pulsations in $p$-modes and $g$-modes simultaneously, and we identify them as $\delta$ Sct–$\gamma$ Dor.
