银河系中HMXB的人口

Population of HMXB in the Galaxy

A. Lutovinov, M. Revnivtsev, M. Gilfanov, R. Sunyaev

摘要:

我们研究人口的大质量X射线双星在银河系中使用的数据的INTEGRAL天文台在硬X射线能量带。在银道面附近(|b| <5度),INTEGRAL探测到了200多个X射线源,其中大部分都是起源于银道面,属于高质量(HMXB)和低质量(LMXB)X射线双星。我们研究了大量HMXB的性质和光谱,并得出结论,其中大部分属于X射线天体。我们还建立了整个银河系的HMXB分布,并表明其峰值实际上与旋臂切线重合。所得到的结果进行了讨论的一些模型估计的密度不同的组成部分的银河系。

英文摘要:

We study populations of High-Mass X-ray Binaries in the Galaxy using data of the INTEGRAL observatory in a hard X-ray energy band. More than two hundreds of sources were detected with INTEGRAL near the galactic plane (|b|<5 deg), most of them have a galactic origin and belong to high (HMXB) and low mass (LMXB) X-ray binaries. We investigated properties and spectra of a large sample of HMXBs and concluded that most of them are belong to X-ray pulsars. We also build the distribution of HMXBs for the whole Galaxy and showed that its peaks are practically coincident with spiral arm tangents. The obtained results are discussed in terms of some model estimations of the density of different components of the Galaxy.
