Abstract

In this study, the possible correlation between compact star clusters and X-ray binaries (XRB) in galaxy NGC 4490, one of the local cluster galaxies, was investigated. 185 tight star clusters were identified after analyzing multi-band HST(Hubble Space Telescope) archive data from 2013 and cluster identification criteria. The clusters ages and masses were calculated by applying the most appropriate SSP (Simple Stellar Population) model to these clusters. As a result of the analysis of 8 Chandra archive data, 91 XRB sources with radiations of 1.5E36 < Lx < 3.5x10E39 erg s-1 were identified. Based on their optical counterparts and the information in the color-color diagrams created, these XRBs were classified as LMXB (Low Mass X-Ray Binaries) or HMXB (High Mass X-Ray Binaries).

Özet

Bu çalışmada, yerel küme ötesi galaksilerden biri olan NGC 4490 galaksisinin sıkı yıldız kümeleri ve X-ışın çiftleri (XRB) arasındaki olası bağıntı araştırıldı. 2013 yılına ait çok bantlı HST arşiv verilerinin analizi ve küme belirleme kriterleri uygulamalarından sonra 185 sıkı yıldız kümesi tanımlandı. Bu kümelere en uygun SSP (Simple Stellar Population) modeli ile kümelerin yaş ve kütle değerleri belirlendi. 8 Chandra arşiv verisinin analizi sonucu ışıtmaları 1.5E36<Lx<3.5E39 erg s-1 olan 91 XRB kaynağı belirlendi. Bu XRB’ler, optik karşılıklarının olup olmadığına ve oluşturulan renk-renk diyagramlarındaki bilgileri doğrultusunda LMXB veya HMXB olarak sınıflandırıldı. Devam eden tez çalışmamızın sonraki aşamasında, belirlediğimiz kümelerle bu XRBlerin olası ilişkileri araştırılacak ve bu kaynakların doğası tartışılacaktır.
