cds-question@unistra.frsupernovaephotometrySome observations suggest that very massive stars experience extreme mass-loss episodes shortly before they explode as supernovae as do several models. Establishing a causal connection between these mass-loss episodes and the final explosion would provide a novel way to study pre-supernova massive-star evolution. Here we report observations of a mass-loss event detected 40 days before the explosion of the type IIn supernova SN 2010mc (also known as PTF 10tel).2013Natur.494...65Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/Nat/494.65CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/313 : Palomar Transient Factory (PTF) photometric catalog 1.0 (Ofek+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/Nat/494.65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/Nat/494.65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/Nat/494.65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/Nat/494.65https://vizier.iucaa.in/viz-bin/votable?-source=J/other/Nat/494.65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/Nat/494.65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/other/Nat/494.65/tables1SN2010mc (PTF10tel) photometric measurementsrecnoRecord number assigned by the VizieR team.
