cds-question@unistra.frinfrared-photometryvisible-astronomyWide-band photometrysupernovaeOn 2017 March 11, the DLT40 Transient Discovery Survey discovered SN2017cbv in NGC 5643, a Type 2 Seyfert Galaxy in the Lupus Constellation. SN 2017cbv went on to become a bright Type Ia supernova, with a Vmax of 11.51+/-0.05mag. We present early time optical and infrared photometry of SN 2017cbv covering the rise and fall of over 68 days. We find that SN 2017cbv has a broad light curve {Delta}m_15_(B)=0.88+/-0.07, a B-band maximum at 2457840.97+/-0.43, a negligible host galaxy reddening where E(B-V)_host_~0, and a distance modulus of 30.49+/-0.32 to the SN, corresponding to a distance of 12.58_-1.71_^+1.98^Mpc. We also present the results of two different numerical models we used for analysis in this paper: SALT2, an empirical model for Type Ia supernova optical light curves that accounts for variability components; and SNooPy, the CSP-II light-curve model that covers both optical and near-infrared wavelengths and is used for distance estimates.2018ApJ...863...90Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/863/90CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)J/A+A/415/863 : Mount Stromlo Abell Cluster SN Search (Germany+, 2004)J/AJ/128/16 : HIPASS Bright Galaxy Catalog (Koribalski+, 2004)J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007)J/ApJ/689/377 : PAIRITEL SNIa as NIR standard candles (Wood-Vasey+, 2008)J/ApJ/696/870 : Catalina Real-time Transient Survey (CRTS) (Drake+, 2009)J/AJ/142/156 : The CSP (DR2): photometry of SNe Ia (Stritzinger+, 2011)J/MNRAS/469/3688 : CSS Periodic Variable Star Catalogue (Drake+, 2017)J/AJ/154/211 : CSP (DR3): photometry of low-z SNe Ia (Krisciunas+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/863/90https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/863/90http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/863/90https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/863/90https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/863/90http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/863/90GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap2.367228618189496e-19 4.920466254354166e-19OpticalInfrareddefaultJ/ApJ/863/90/table5Optical and near-IR photometric cadence of SN2017cbvrecnoRecord number assigned by the VizieR team.
