Abstract

Bu çalışmada Samanyolu'nun oluşumu ve evrimi Geciken İkili Çökme Modeli kullanılarak araştırılmıştır. APOGEE, GALAH ve Gaia gökyüzü taramalarından hassas bir şekilde seçilen yıldız örneği kullanılarak galaksi merkezinden düzlemne 5-11 kpc uzaklığı arasındaki disk bölgesi 2 kpc genişliğinde üç bölgeye ayrılarak beş element için modellenmiş ve modelden elde edilen bilgiler gözlemsel bulgularla karşılaştırılmıştır. Çalışmada elde edilen gözlemsel ve modelsel gradyent sonuçları ince disk için literatürle uyumlu sonuçlar elde edilirken kalın disk için literatürden farklı olarak hassas negatif bir radyal element bolluğu gradyenti elde edilmiştir. Modelden elde edilen sonuçlar literatürdeki genel kanının aksine Galaksi diskinin oluşumunun dıştan içe bir oluşum senaryosuyla açıklanabileceğini göstermektedir.

A Recipe for The Galaxy

Abstract

In this study, the formation and evolution of the Milky Way was investigated using the Delayed Binary Collapse Model. Using a precisely selected star sample from APOGEE, GALAH and Gaia sky scans, the disk region between 5-11 kpc from the galaxy center to the plane was divided into three regions with a width of 2 kpc and modeled for five elements, and the information obtained from the model was compared with the observational findings. While the observational and model gradient results obtained in the study were consistent with the literature for the thin disc, a sensitive negative radial element abundance gradient was obtained for the thick disc, unlike the literature. The results obtained from the model show that contrary to the general belief in the literature, the formation of the Galaxy disk can be explained by an outside-in formation scenario.
