Abstract
In this study, we are aimed to determine the radial velocity and stellar atmospheric parameters such as Teff, logg, [Fe/H] of these stars by using medium resolution spectral data from the LAMOST data archive of some member stars of open star cluster NGC 436. The memberships of the stars were determined from the GAIA EDR3 proper motion data. The GAIA data of the cluster were matched with the UBVRI data from the San Pedro Martir Observatory, and the basic astrophysical parameters of the cluster were examined in many filters. Monte Carlo Markov Chain optimization technique was used in the analysis of spectral data. In addition, the variable types of the stars determined as cluster members were
determined by examining the TESS data.

Abstract
Bu çalışmada, NGC 436 açık yıldız kümesindeki bazı üye yıldızlara ait LAMOST veri arşivinden orta çözünürlükü mevcut tayf verileri kullanılarak bu yıldızlara ait radyal hız ve Teff, logg, [Fe/H] gibi yıldız atmosferik parametrelerinin belirlenmesi amaçlanmıştır. Yıldızların üyelikleri GAIA EDR3 özhareket verilerine göre belirlenmiştir. Kümenin GAIA verileri, San Pedro Martir Gözlemevi’nden alınan UBVRI verileri ile eşleştirilerek kümeye ait temel astrofiziksel parametreler bir çok filtrede incelenmiştir. Tayf verilerinin analizinde Monte Carlo Markov Chain optimizasyon tekniği kullanılmıştır. Ayrıca küme üyesi olarak belirlenen yıldızların TESS verileri incelenerek değişen türleri saptanmıştır.
