Identifying Progenitors of Two Peculiar SNRs in the LMC and SMC with the RGS

Last few years, we have presented various results of highresolutionspectroscopies of SNRs with the RGS. Although a large amount of the archivaldata over the past twenty years is available and most of the notable SNRs havebeen observed with the RGS, several intriguing remnants are still not observed.A recent comprehensive systematic analysis of SNRs revealed that a clearcorrelation between their morphologies and supernova types. We, however, foundtwo outliers in the correlation diagram\\: 054870.4 and 010472.3, which areminor LMC/SMC SNRs but have anomalous abundance pattern and peculiarmorphologies. We thus propose to observe these SNRs with the RGS to give aconclusive result on their origin and nature. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
