Abstract

We have analyzed an observation of the supernova remnant N132D in the Large Magellanic Cloud, performed with the Low Energy Concentrator Spectrometer (LECS) and the Medium Energy Concentrator Spectrometer (MECS) instruments on board the X-ray satellite BeppoSAX. Thanks to the good sensitivity of the LECS/MECS combination over the range 0.3-8.5 keV we were able to detect the presence of an additional hotter plasma with respect to what had been previously assumed for this remnant. This hotter component is the source of the Fe-K line emission visible in the spectrum. Using a two component NEI plasma model we find that the best fitting abundance values indicate that N132D is also O-rich from the X-ray point of view. We briefly discuss the origin of the hot component and tentatively associate it with a radio bright region.

Key words: ISM: abundances; ISM: individual objects: N132D: ISM: supernova remnants: X-rays: ISM
