Description
It is extremely rare when a binary is found to be associated with supernova remnant. It is also rare when a high-mass binary is bright in gamma-rays. SNR G284.3-1.8 appears to be a unique remnant hosting such a binary. We present results from Chandra and XMM-Newton observations of the SNR and the binary. G284.3-1.8 has asymmetrically distributed Mg-rich ejecta, which has only been observed in one other remnant. It also appears to be interacting with a molecular cloud in the north. It is clear that the SN progenitor was a massive star, but the unknown nature of the compact object complicates the binary evolution modeling. We will report the variability and spectral analysis for the binary X-ray emission and discuss the constraints our results place on the SNR progenitor system and the high-mass binary evolution scenarios.
