cds-question@unistra.frsupernova-remnantshst-photometryx-ray-sourcesmagellanic-cloudsWe present the results of a search for an ex-companion star in SNR 0519-69.0, located in the Large Magellanic Cloud, based on images taken with the Hubble Space Telescope with a limiting magnitude of V=26.05. SNR 0519-69.0 is confidently known to be from a Type Ia supernova based on its light echoes and X-ray spectra. The geometric center of the remnant (based on the H{alpha} and X-ray shell) is at 05:19:34.83, -69:02:06.92 (J2000). Accounting for the measurement uncertainties, the orbital velocity, and the kick velocity, any ex-companion star must be within 4.7" of this position at the 99.73% confidence level. This circle contains 27 main-sequence stars brighter than V=22.7, any one of which could be the ex-companion star left over from a supersoft source progenitor system. The circle contains no post-main-sequence stars, and this rules out the possibility of all other published single-degenerate progenitor classes (including symbiotic stars, recurrent novae, helium donors, and the spin-up/spin-down models) for this particular supernova. The only remaining possibility is that SNR 0519-69.0 was formed from either a supersoft source or a double-degenerate progenitor system.2012ApJ...747L..19Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/747/L19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2013)B/hst : HST Archived Exposures Catalog (STScI, 2007)J/MNRAS/426/2668 : Soft X-ray emission of Ia SN progenitors (Nielsen+, 2012)J/MNRAS/408/827 : Simulations of supernova explosions (Dessart+, 2010)J/A+A/435/437 : Diameters for extragalactic SNRs (Urosevic+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/747/L19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/747/L19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/747/L19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/747/L19https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/747/L19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/747/L19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/747/L19/table2 (Stars inside the central error circle for SNR 0519-69.0)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/747/L19/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/747/L19/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/747/L19/table2?GETtext/xml+votable180.050000true77.3938375-69.036861110.0055555555555555566/330983.5070461021726235e-19 3.611048890148178e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/747/L19?format=asciiX-raydefaultJ/ApJ/747/L19/table2Stars inside the central error circle for SNR 0519-69.0recnoRecord number assigned by the VizieR team.
