Session 46 - Supernova Remnants.
Display session, Tuesday, January 14
In a kinematic study of LMC H\,\sc ii regions, we serendipitously found a fast-expanding shell in the luminous H\,\sc ii region N159. The expansion pattern and the [S\,\sc ii]/H\alpha ratio of the shell are consistent with those seen in supernova remnants (SNRs). Confirmation of this SNR candidate in radio and X-ray wavelengths has been hampered by thermal emission of the luminous H\,\sc ii region N159 itself and scattered X-rays from the nearby luminous source LMC\,X-1. Recent ROSAT observations finally resolved N159 from LMC\,X-1, thus confirming the identification of the new SNR, designated SNR\,0540-697.
