By measuring the morphology of the Chandra X-ray line emission in seventeen Galactic and Large Magellanic Cloud SNRs with a multipole expansion analysis (using power ratios), we find that the core-collapse SNRs are statistically more asymmetric than the Type Ia SNRs. We show that the two classes of supernovae can be separated naturally using this technique because X-ray line morphologies reflect the distinct explosion mechanisms and structure of the circumstellar material. These findings are consistent with recent spectropolarimetry results showing that core-collapse SNe are intrinsically more asymmetric.", "revisions": [ { "version": "v1", "updated": "2009-10-19T18:06:10.000Z" } ], "analyses": { "keywords": [ "morphology", "x-ray line emission morphologies", "typing supernova remnants", "x-ray line morphologies reflect", "chandra x-ray line emission" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0004-637X/706/1/L106", "journal": "The Astrophysical Journal", "year": 2009, "month": "Nov", "volume": 706, "number": 1 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 834265, "adsabs": "2009ApJ...706L.106L" } } }
