What is the nature of the central compact X-ray source in the supernova remnant RCW 103

TL;DR

This paper analyzes the nature of the central X-ray source in supernova remnant RCW 103, favoring a model where an accreting neutron star in a disrupted binary system explains the observations.

Contribution

It proposes that the central X-ray source is most likely an accreting neutron star within a disrupted binary system, advancing understanding of such sources in supernova remnants.

Findings

The source is more likely an accreting neutron star than a black hole.

A disrupted binary system model explains the observed properties.

The model aligns with the observed 69-ms pulsar signals.

Abstract

In this poster I discuss the nature of the compact X-ray source in the center of the supernova remnant RCW 103. Several models, based on the accretion onto a compact object such as a neutron star or a black hole (isolated or binary), are analyzed. I show that it is more likely that the central X-ray source is an accreting neutron star than an accreting black hole. I also argue that models of a disrupted binary system consisting of an old accreting neutron star and a new one observed as a 69-ms X-ray and radio pulsar are most favored.
