Nova M31N 2012-05c found as a supersoft X-ray source with XMM-Newton
Abstract
We report the serendipitous discovery of a supersoft X-ray source (SSS) counterpart to the recent optical nova M31N 2012-05c in M 31. The optical outburst of the object (alternative name: PNV J00423149+4126138) was discovered by K. Hornoch (ATel#4096) and it was subsequently confirmed as a nova using Hα observations (Hornoch, ATel#4181). We detected the X-ray counterpart with (7.6±0.2) × 10-2 ct s-1 in a 25 ks XMM-Newton target of opportunity (ToO) observation of a region north of the M 31 centre on 2012-08-08.96 UT.
