1999A&A...344L..13O

Nova LMC 1995 was detected with ROSAT as an X-ray source in repeated observations between 1995 and 1998, starting five months after the outburst. In February 1998, 3 years after the nova outburst, ROSAT PSPC data show that this is the only LMC post-nova - and one out of three among ≃100 altogether - that appeared as a bright supersoft X-ray source after the outburst. The PSPC data are satisfactorily fitted with an LTE carbon-oxygen atmosphere model for a 1.2M_☉ white dwarf, resulting in an effective temperature about 30eV. The X-ray flux increased in the last years and at present Nova LMC 1995 is about twice as bright as in a 1996 observation. We suggest that the photosphere is still shrinking and the remnant becoming hotter. Such a nova is a likely type Ia SN progenitor.
