Abstract
Bu çalışmada, Ejderha Takımyıldızı’nda bulunan ve 102.7 pc uzaklıkta yer alan F2 tayf türündeki HD 132560 yıldızının atmosfer parametreleri belirlendi. Yıldızın tayfsal gözlemleri, Ankara Üniversitesi Kreiken Rasathanesi'ndeki T40 teleskobu kullanılarak gerçekleştirilmiş olup, IRAF yazılımıyla veri indirgeme işlemleri yapılmıştır. Analizlerde Python tabanlı Speedysedfit ve SteParSyn paketleri kullanılarak etkin sıcaklık (Teff), yüzey çekim ivmesi (log g), metal bolluğu ([Fe/H]) ve tayf genişleme hızı (Vbroad) hesaplanmıştır. Sonuçlar Gaia ve TESS veritabanlarındaki katalog değerleriyle uyumlu olup, [Fe/H] ve Vbroad parametreleri ilk kez belirlenmiştir.

Abstract
In this study, the atmospheric parameters of the F2 spectral type star HD 132560, located in the constellation Draco at a distance of 102.7 pc, were determined. Spectral observations of the star were obtained using the T40 telescope at Ankara University Kreiken Observatory, and data reduction processes were performed using the IRAF software. The Python-based Speedysedfit and SteParSyn packages were used in the analyses to calculate the effective temperature (Teff), surface gravity (log g), metallicity ([Fe/H]), and spectral broadening velocity (Vbroad). The results are consistent with catalog values in the Gaia and TESS databases, and the [Fe/H] and Vbroad parameters were determined for the first time.
