The spectral analysis of the transitional millisecond pulsar J1023+0038

Abstract

PSR J102347.6 +003841 (also known as PSR J1023) is one of three known transitional millisecond pulsars (tMSP). We analyze EPIC X-ray data from the XMM-Newton satellite to probe multiple X-ray states of this star. By analyzing a combined total of 18 bservations across multiple years, we hope to provide a comprehensive picture of the spectral properties of this source and analyze the effectiveness of various models in successfully describing its behavior. We perform the spectral fitting and modeling of the source using the spectral modeling software XSPEC and other tools within the publicly available Heasoft package.
