Spectral and Timing Analysis of Radio Quiet X-Ray source 1E 161348-5055.1 using XMM Newton Mission

Abstract

Neutron stars are remnants of supernovae explosion of massive stars upto 20-40 Mʘ at the time of their formation, neutron stars gain recoil kicks due to asymmetries that develops during the core-collapse process. Neutron stars are classified as Radio Loud and Radio Quiet. 1E 161348-5055.1 is a radio quiet neutron star found in the Centre of RCW103 which is Supernova Remnant (SNR) and is a periodic X-Ray with a period of 6.67 hours. This source was discovered by the HEAO-2 (Einstein Observatory), which is the first fully imaging XRay telescope. This source attracted interest due to the two main reasons. Firstly, its periodicity of 6.67 hrs which is too long for star having age 2000 years, it is behaving like a multi-million-year-old star. Secondly, the star becomes 50 times brighter in between October 1999 and January 2000. Astrophysicist put forward many theories to explain this phenomenon. In present work, the author downloaded one archived data from XMM Newton Mission and analyzed it as well as reviewed the works related to this source to understand the nature of the neutron star 1E 161348-5055.1.
