cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometrySN 2013dy is a Type Ia supernova (SN Ia) for which we have compiled an extraordinary data set spanning from 0.1 to ~500d after explosion. We present 10 epochs of ultraviolet (UV) through near-infrared (NIR) spectra with Hubble Space Telescope/Space Telescope Imaging Spectrograph, 47 epochs of optical spectra (15 of them having high resolution), and more than 500 photometric observations in the BVrRiIZYJH bands. SN 2013dy has a broad and slowly declining light curve ({Delta}m_15_(B)=0.92mag), shallow SiII {lambda}6355 absorption, and a low velocity gradient. We detect strong CII in our earliest spectra, probing unburned progenitor material in the outermost layers of the SN ejecta, but this feature fades within a few days. The UV continuum of SN 2013dy, which is strongly affected by the metal abundance of the progenitor star, suggests that SN 2013dy had a relatively high-metallicity progenitor. Examining one of the largest single set of high-resolution spectra for an SN Ia, we find no evidence of variable absorption from circumstellar material. Combining our UV spectra, NIR photometry, and high-cadence optical photometry, we construct a bolometric light curve, showing that SN 2013dy had a maximum luminosity of 10.0^+4.8^_-3.8_x10^42^erg/s. We compare the synthetic light curves and spectra of several models to SN 2013dy, finding that SN 2013dy is in good agreement with a solar-metallicity W7 model.2015MNRAS.452.4307Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/452/4307CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)J/AJ/151/125 : Optical and UV photometry of SN 2013dy (Zhai+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/452/4307https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/452/4307http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/452/4307https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/452/4307https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/452/4307http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/452/4307GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap1.1019998519292435e-19 4.920466254354166e-19OpticalInfrareddefaultJ/MNRAS/452/4307/table1KAIT photometry of SN 2013dyrecnoRecord number assigned by the VizieR team.
