Abstract

In this work, using the T80 Prof. Dr. Berahitdin Albayrak Telescope and its attached spectrograph, high resolution (R$\approx$30000) spectra at different rotational phases of the Ap type magnetic-chemically peculiar star CQ UMa were obtained. Atmospheric parameters of CQ UMa were determined with the help of the analysis of the spectral data and compared with the studies in the literature, and it's correlation of TESS lightcurve data with the abundance distributions of some elements were examined.

CQ UMa’nın Atmosferik Parametrelerinin Belirlenmesi

Abstract

Bu çalışmada, Ankara Üniversitesi Kreiken Rasathanesi’nde bulunan T80 Prof. Dr. Berahitdin Albayrak Teleskobu ve ona bağlı tayfçeker kullanılarak Ap türü manyetik kimyasal tuhaf CQ UMa yıldızının farklı dönme evrelerinde yüksek çözünürlüklü (R$\approx$30000) tayfları elde edildi. Tayfsal verilerin analizleri yardımıyla CQ UMa'nın atmosferik parametreleri belirlenip literatürdeki çalışmalarla karşılaştırıldı ve TESS ışık eğrisi verileri ile bazı elementlerin bolluk dağılımlarıyla korelasyonu incelendi.
