Galaksimizdeki 20 Açık Yıldız Kümesinin CCD UBVRI Fotometrisi

Year 2020, Volume: 1 Issue: 1, 229 - 231, 11.12.2020

Abstract

Bu çalışmada Meksika San Pedro Martir (SPM) Ulusal Astronomi Gözlemevi'nde 84 cm teleskop ile gözlenmiş 20 açık yıldız kümesinin CCD UBVRI fotometrisi verileri ile gözlemsel parametreleri olan renk artıkları, metal ve ağır element bollukları, uzaklık modülleri, uzaklıkları ve yaşları elde edilmiştir. Metal bolluğu tayini, $(U-B)$-$(B-V)$ iki renk diyagramında Hyades anakolu üzerindeki metalce fakir parlak F tayf türünden yıldızların dağılımlarından belirlenen $\delta(U$--$B)$ morötesi artığı tekniğiyle yapılmıştır. 20 kümenin uzaklık modülü, uzaklık ve yaşları, eşyaş eğrilerinin kümelerin beş renk indeksindeki ($B-V$, $R-I$, $V-R$, $V-I$, $B-R$) renk-kadir diyagramları ile çakıştırılmasından elde edilmiştir.
