Examination Of The X-ray Spectrum From The SNR 0509-67.5
Abstract
We report on X-ray observations of the supernova remnant 0509-67.5 in Large Maggelanic Clouds with XMM-Newton. The Reflective Grating Spectrometer data show that the remnant has a very high expansion velocity of 6000 km/s. The imaging spectroscopy data (EPIC) show that the remnant has an asymmetric ejecta structure: the bright southwest region of the remnant shows an overabundance of Si, S, Fe. This could be a sign of an asymmetric explosion or it could be the result of a density enhancement of the ISM in the Southwest. In addition to the data analysis we also present a hydrodynamical modeling of the remnant. The simulations allow us to put some additional constraints on the SNR properties and density of the environment.
