Kj. Van Der Hyden et al., Detection of X-ray line emission from the shell of SNR B0540-69.3 with XMM-Newton RGS, ASTRON ASTR, 365(1), 2001, pp. L254-L258
We present X-ray observations of PSR 0540-69.3 with the XMM-Newton observat
ory. The spectra obtained with the Reflection Grating Spectrometer reveal,
for the first time, emission from ionized species of O, Ne and Fe originati
ng from the SNR shell. Analysis of the emission line spectrum allows us to
derive estimates of the temperature, ionization timescale, abundances, loca
tion, and velocity of the emitting gas.
