4U 1323 -619的红外鉴定
Infrared identification of 4U1323-619 revisited
摘要:
我们重新研究了倾斜的低质量x射线双星4U 1323 -619的红外对应物。XMM和钱德拉天文台提供的新X射线数据与ESO 3.6米新技术望远镜的档案红外观测相结合,使我们能够定义一个新的可能的对应物。在这里,我们提出了它的光度特性,并将它们与一个简单的分析模型的吸积盘照亮的热中心电晕已知存在于二元系统。
英文摘要:
We re-examine the infrared counterpart of the dipping low-mass x-ray binary 4U1323-619. New X-ray data available from the XMM and Chandra observatories combined with archival IR observations from the ESO 3.6m New Technology Telescope allow us to define a new possible counterpart. We present here its photometric properties and compare them with a simple analytical model of an accretion disc illuminated by the hot central corona known to be present in the binary system.
