However, the full progenitor system and the process that prompts the white dwarf to explode remain unknown. Most current models suggest that the white dwarf explodes because of interaction with a binary companion which may survive the process and remain within the resulting remnant of the exploded star. Furthermore, the interaction and explosion of the primary are expected to imprint a significant departure from ordinary stellar radii and temperatures onto the secondary, making the star identifiable against the unrelated stellar population. Identification of a surviving companion inside an SN Ia remnant might confirm a specific corresponding SN Ia progenitor channel based on the identity of the companion. We conducted a surviving companion search of Type Ia SNR 0509-67.5 based in the Large Magellanic Cloud (LMC). The well-constrained distance to and foreground extinction of the LMC allow for Bayesian inference of stellar parameters with low correlation and uncertainties. We present a deep catalog of fully characterized stars interior to SNR 0509-67.5 with radii, effective temperatures, and metallicities inferred using combined Hubble Space Telescope photometric observations across multiple visits. We then compile a list of surviving companion models appropriate for the age of the remnant (roughly 400 years after the explosion). We compare these predictions with the inferred stellar parameters and conclude that none of the stars are consistent with the predicted signatures of a surviving companion.2023ApJ...950L..10Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/950/L10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/950/L10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/950/L10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/950/L10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/950/L10https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/950/L10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/950/L10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/950/L10/hscparam (Photometry and parameters for objects identified in the Hubble Source Catalog near the center of SNR 0509-67.5, as well as the immediate nearby surrounding stellar population (table 4))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/950/L10/hscparam?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/950/L10/hscparam?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/950/L10/hscparam?GETtext/xml+votable180.050000true77.3768893054567-67.52006338862060.0055555555555555566/331241.0590977079788917e-19 4.9761815603361e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/950/L10?format=asciidefaultJ/ApJ/950/L10/hheparamPhotometry and parameters for objects identified in Arunachalam et al.
