Abstract

X-ışın çiftlerinin taç bölgesinin doğası ve Compton saçılmasının kritik bileşeni olan düşük enerjili fotoların temelini oluşturan geometrik yapısı ile ilgili araştırmalar son yıllarda büyük ivme kazanmıştır. Bu nedenle bileşenlerinden biri Nötron Yıldız (NY) veya Kara delik (KD) olan sistemlerin özellikle düşük ışımagücü ($\lesssim10^{35}$ erg s$^{-1}$) bölgesindeki benzerlik ve farklılıklarının araştırılması oldukça önemlidir. Bu çalışmada, LMXB'lerde tayfsal indis ve X-ışın ışımagücü arasında olduğu bilinen ilişki geniş ışımagücü aralığında farklı KD (2S 0921-63, 4U 1957+11) ve NY (4U 1608-52, MAXI J1807+132) sistemleri için {\it NICER}, {\it SWIFT}, ve {\it XMM-Newton} uydu verileri kullanılarak incelenmiştir. KD ve NY sistemleri için genel olarak gözlenen ilişkinin incelenen kaynak özelliklerini uzun dönemli gözlemler için de temsil ettiği görülmüştür.

Abstract

Studies of the nature and geometrical profile of the corona, thought to be the site of Compton scattering, continues to be of considerable interest in both the high and low-luminosity X-ray scattering. In this work, we study the behavior of neutron star (NS) and black hole (BH) LMXB systems in the low-luminosity region ($\lesssim10^{35}$ erg s$^{-1}$). In particular, we investigate the relationship between the spectral index and the X-ray luminosity of four different BH (2S 0921-63, 4U 1957+11) and NS (4U 1608-52, MAXI J1807+132) systems using {\it NICER}, {\it SWIFT}, and {\it XMM-Newton} data. Our analysis suggests that the generic correlation survives for these individual sources in their long-term behavior.
