cds-question@unistra.frsupernovaestellar-distanceinterstellar-reddeningWe present a new self-consistent and versatile method that derives photospheric radius and temperature variations of Type II-Plateau supernovae based on their expansion velocities and photometric measurements. We apply the method to a sample of 26 well-observed, nearby supernovae with published light curves and velocities. We simultaneously fit ~230 velocity and ~6800mag measurements distributed over 21 photometric passbands spanning wavelengths from 0.19 to 2.2{mu}m. The light-curve differences among the Type II-Plateau supernovae are well modeled by assuming different rates of photospheric radius expansion, which we explain as different density profiles of the ejecta, and we argue that steeper density profiles result in flatter plateaus, if everything else remains unchanged. The steep luminosity decline of Type II-Linear supernovae is due to fast evolution of the photospheric temperature, which we verify with a successful fit of SN 1980K. Eliminating the need for theoretical supernova atmosphere models, we obtain self-consistent relative distances, reddenings, and nickel masses fully accounting for all internal model uncertainties and covariances. We use our global fit to estimate the time evolution of any missing band tailored specifically for each supernova, and we construct spectral energy distributions and bolometric light curves. We produce bolometric corrections for all filter combinations in our sample. We compare our model to the theoretical dilution factors and find good agreement for the B and V filters. Our results differ from the theory when the I, J, H, or K bands are included. We investigate the reddening law toward our supernovae and find reasonable agreement with standard R~3.1 reddening law in UBVRI bands. Results for other bands are inconclusive. We make our fitting code publicly available.2015ApJ...799..215Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/799/215CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)J/ApJ/799/208 : Type IIP supernovae from Pan-STARRS1 (Sanders+, 2015)J/MNRAS/442/844 : Type II-P supernovae BVRI light curves (Faran+, 2014)J/A+A/558/A131 : Model spectra of hot stars at the pre-SN stage (Groh+, 2013)J/ApJS/208/9 : Intrinsic colors & temperatures of PMS stars (Pecaut+, 2013)J/MNRAS/433/1871 : UBVRI griz light curves of SN 2012aw (Bose+, 2013)J/A+A/555/A142 : Spectra of 5 Type II supernovae (Inserra+, 2013)J/other/NewA/20.30 : BVRI light curves of 3 SN (Munari+, 2013)J/ApJ/708/661 : SDSS-II SN Survey: SN II-P standardization (D'Andrea+, 2010)J/MNRAS/394/2266 : SN 2005cs one-year photometry (Pastorello+, 2009)J/ApJ/673/999 : Supernova and host galaxies metallicities (Prieto+, 2008)J/other/PZ/28.8 : SN 2004dj UBVRI light curves (Tsvetkov+, 2008)J/MNRAS/372/1315 : UBVRI photometry of SN 2004et (Sahu+, 2006)http://wiserep.weizmann.ac.il/ : Weizmann Interactive Supernova data REPositoryhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/799/215https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/799/215http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/799/215https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/799/215https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/799/215http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/799/215GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/799/215/SNIIp (Studied SNIIp, with luminosities and Ni mass ejected)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/799/215/SNIIp?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/799/215/SNIIp?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/799/215/SNIIp?GETtext/xml+votable180.050000true308.875291760.10658330.005555555555555556Cone search capability for table J/ApJ/799/215/table5 (Galaxy distances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/799/215/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/799/215/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/799/215/table5?GETtext/xml+votable180.050000true202.46957547.19525830.0055555555555555566/611 3861 5629 5715 7743 9437 10723 10991 11027 11492 15592 15593 16441 17637 19710 20720 22751 25344 25431 25438 26303 27514 27515 27643 27955https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/799/215?format=asciiOpticaldefaultJ/ApJ/799/215/SNIIpStudied SNIIp, with luminosities and Ni mass ejectedrecnoRecord number assigned by the VizieR team.
