中子星低质量X射线双星的X射线视图

X-ray views of neutron star low-mass X-ray binaries

Sudip Bhattacharyya

摘要:

中子星低质量X射线双星是一个由一颗中子星和一颗低质量伴星围绕彼此旋转的双星系统。在这个系统中,中子星从伴星吸积质量,当这些物质落入中子星的深势阱时,引力势能主要在X射线波长内释放。1962年首次在X射线中发现了这种源,这一发现正式催生了“X射线天文学”。在随后的几十年里,通过几次X射线太空任务的观测,我们对这些来源的了解大大增加。在这里,我们给出了我们目前的理解这些系统的X射线观测方面的简要概述。

英文摘要:

A neutron star low-mass X-ray binary is a binary stellar system with a neutron star and a low-mass companion star rotating around each other. In this system the neutron star accretes mass from the companion, and as this matter falls into the deep potential well of the neutron star, the gravitational potential energy is released primarily in the X-ray wavelengths. Such a source was first discovered in X-rays in 1962, and this discovery formally gave birth to the "X-ray astronomy". In the subsequent decades, our knowledge of these sources has increased enormously by the observations with several X-ray space missions. Here we give a brief overview of our current understanding of the X-ray observational aspects of these systems.
