A paper on plasma diagnosis by high-resolution X-ray spectroscopic analysis of supernova remnant N132D using the XMM-Newton satellite RGS diffraction grating by Hitomi Suzuki was published in ApJ.。

N132D is the gravitational collapse type supernova remnant that shines brightest on X-rays in the Large Magellanic Cloud.、The XMM-Newton satellite is primarily intended for on-board calibration of detectors.、I observe this object regularly。In this study、XMM-Newton satellite RGS detector data 9 observations (total 199 ksec) Against、Perform model fitting and plasma diagnosis、I explored the plasma state of N132D。as a result 0.3-2 The X-ray spectrum of keV shows an "ionization non-equilibrium state" in which the degree of ionization does not reach the electron temperature.、It turns out that the abundance is about the interstellar medium of the Large Magellanic Cloud.。Also、Based on the emission line intensity ratio、We are also discussing the possibility of charge exchange reactions and resonance scattering.。
