dc.description.abstractPulsating 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 delta 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 delta 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 T-eff and logg range. The delta Scuti stars generally have T-eff and log g value in a range of 6300-8500 K and 3.2-4.3, respectively. Hence, we selected the stars which have TIC T-eff and logg values in these ranges. The other criterion is the pulsating frequency. A frequency analysis was performed for all the candidate stars. In addition, M-V, L and also M-bol parameters of the target stars were determined to calculate the pulsation constants and show their positions in the H-R diagram. The final pulsation type classification was made by considering the frequency ranges and pulsation constants of the stars. As a result of the study, five delta Scuti, one gamma Doradus and four hybrid systems were discovered.
