Identified one Gamma Doradus star.
Found four hybrid pulsating systems.
Abstract
Pulsating stars are remarkable objects for stellar astrophysics. Their pulsation frequencies allow us to probe the internal structure of stars. One of the most known groups of pulsating stars is Scuti variables which could be used to understand the energy transfer mechanism in A-F type stars. Therefore, in the current study, we focused on the discovery of Scuti stars. For this investigation, we followed some criteria. First, we inspected TESS database by eye and discovered some single stars that exhibit pulsation-like behaviour. Our second criterion is and range. The Scuti stars generally have and value in a range of 6300\,\,8500\,K and 3.2\,\,4.3, respectively. Hence, we selected the stars which have TIC and values in these ranges. The other criterion is the pulsating frequency. A…
