Özet

Pulsations in chemically peculiar stars were not expected decades ago. Detailed studies of some of these objects proofed that chemically peculiar stars do pulsate. Most of the chemically peculiar stars show Delta Scuti type pulsations. The recent studies of Kepler and TESS field Delta Scuti stars showed us that pulsation mechanism in these Delta Scuti variables has not totally understood. To explain the present pulsation mechanism in Delta Scuti stars, especially in chemically peculiar Delta Scuti stars, pulsation models of these variables need some precise parameters such as effective temperature, metallicity. Therefore, in this study, a detailed analysis of some chemically peculiar Delta Scuti stars is presented. The atmospheric parameters of the stars were derived and the pulsation characteristic was examined in detail to find out the effects of some atmospheric parameters to the pulsations of chemically peculiar Delta Scuti stars.
