X-ray studies of radio-silent neutron stars in the remnants of supernova explosions

TL;DR

This study analyzes X-ray observations of a neutron star within a supernova remnant, measuring its temperature and spectral properties over time to understand its physical characteristics.

Contribution

The paper provides detailed spectral analysis of the neutron star G350.1-0.3 using Chandra data from 2009 and 2018, including temperature measurements and plasma modeling.

Findings

Neutron star temperature measured in two different years.

Spectral analysis using VNEI plasma model.

Insights into supernova remnant properties.

Abstract

The present work is devoted to the study of the supernova remnant and its neutron star XMMU J172054. 5-372652. The paper analyzes observations in 2009 and 2018, data for this system obtained by the Chandra x ray observatory. The analysis showed that the neutron star G350. 1-0. 3 with M = 1, 4 Msun, R = 13 MS, dist = 4, 5 KPC, we also measured its temperature in two groups: the first group, including observations made in 2009, and the second group, including 5 observations made at different times of the year 2018. In addition, in this work, we study all important aspects of the supernova remnants of G350. 1-0. 3, and obtain their spectra using the collided plasma, nonequilibrium, constant temperature (VNEI) model, which assumes a constant temperature and a single ionization parameter. It gives a characteristic of the spectrum, but is not a physical model, we will precede the spectra obtained using this model.
