cds-question@unistra.frinfrared-photometryvisible-astronomyphotometrysupernovaeWe present the discovery of PTF 10vgv, a Type Ic supernova (SN) detected by the Palomar Transient Factory, using the Palomar 48 inch telescope (P48). R-band observations of the PTF 10vgv field with P48 probe the SN emission from its very early phases (about two weeks before R-band maximum) and set limits on its flux in the week prior to the discovery. Our sensitive upper limits and early detections constrain the post-shock-breakout luminosity of this event. Via comparison to numerical (analytical) models, we derive an upper-limit of R<~4.5R_{sun}_ (R<~1R_{sun}_) on the radius of the progenitor star, a direct indication in favor of a compact Wolf-Rayet star. Applying a similar analysis to the historical observations of SN 1994I yields R<~1/4R_{sun}_ for the progenitor radius of this SN.2012ApJ...747L...5Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/747/L5CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/313 : Palomar Transient Factory (PTF) photometric catalog 1.0 (Ofek+, 2012)J/ApJ/728/14 : Photometry of SN 2009bb (Pignata+, 2011)J/A+A/508/371 : UBVRIJHK observations of SN 2007gr (Hunter+, 2009)J/MNRAS/383/1485 : BVRI light curves of SN 2003jd (Valenti+, 2008)J/ApJ/687/1201 : SN and LGRB locations in their host galaxies (Kelly+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/747/L5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/747/L5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/747/L5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/747/L5https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/747/L5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/747/L5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap2.762881831355591e-19 3.3785437584409506e-19OpticalInfrareddefaultJ/ApJ/747/L5/table1P48 Observations of PTF 10vgv in R-bandrecnoRecord number assigned by the VizieR team.
