XMM - Newton observations of Nova LMC 2000 ⋆
We report on three X-ray observations of Nova LMC 2000 with XMM-Newton at 17, 51 and 294 days after the maximum, respectively. X-ray spectral fits show a concordant decrease of the absorbing column and the X-ray luminosity. No supersoft X-ray emission is detected. The mass of the ejected shell is determined to be (less than) 7.5 × 10 −5 M⊙. Though data are sparse, one interesting correlation be...
متن کاملThe incidence of spontaneous abortion in mothers with blood group O compared with other blood types
Although ABO incompatibility between mother and fetus has long been suspected as cause of spontaneous abortion in man, its precise contribution has not been completely resolved. In spite of reports in which the incompatible mating was recognized to be a cause of habitual abortion, and which eventually results in infertility or a reduction in the number of living children compared with the numbe...
متن کاملOn the occurrence of dwarf nova outbursts in post novae
We show that irradiation of the accretion disc by the white dwarf limits the occurrence of dwarf nova outbursts in post nova accretion discs. After the nova explosion, the white dwarf has to cool for up to ∼ 100 yr – depending on the orbital period (i.e., disc size) and the temperature of the white dwarf after the nova-eruption – before the disc can begin producing dwarf nova outbursts. During ...
متن کاملLMC 1995 , the third supersoft X - ray nova
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 satisfact...
متن کاملThe Local Stellar Population of Novae Regions in the Large Magellanic Cloud
The distribution of novae across the face of the Large Magellanic Cloud (LMC) is presented. The star formation history of nearby regions around them is also studied using photometric data of stars and star clusters in the OGLE II survey and star cluster catalogues. The nova population in the LMC belong, predominantly, to the fast category, with only 11.8% belonging to the slow nova population. ...
