cds-question@unistra.frsupernovaeultraviolet-astronomyvisible-astronomybroad-band-photometryWe present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data analysis on the associated Swift X-ray transient (XRT) 080109. Our data span a time range of 5hr before the detection of the X-ray transient to 150 days after its detection, and a detailed analysis allowed us to derive constraints on the nature of the SN and its progenitor; throughout we draw comparisons with results presented in the literature and find several key aspects that differ. Our data first established that SN 2008D is a spectroscopically normal SN Ib (i.e., showing conspicuous He lines) and showed that SN 2008D had a relatively long rise time of 18 days and a modest optical peak luminosity. The early-time light curves of the SN are dominated by a cooling stellar envelope (for {Delta}t~0.1-4days, most pronounced in the blue bands) followed by ^56^Ni decay.2009ApJ...702..226Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/702/226CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/692/L84 : Photometry of SN 2008D (Malesani+, 2009)http://swift.gsfc.nasa.gov/docs/swift/archive/ : SWIFT archive pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/702/226https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/702/226http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/702/226https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/702/226https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/702/226http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/702/226GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapUVOpticaldefaultJ/ApJ/702/226/table5Swift/UVOT photometry of SN 2008DrecnoRecord number assigned by the VizieR team.
