cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryWe present our observations of SN 2010mb, a Type Ic supernova (SN) lacking spectroscopic signatures of H and He. SN 2010mb has a slowly declining light curve (LC) (~600 days) that cannot be powered by ^56^Ni/^56^Co radioactivity, the common energy source for Type Ic SNe. We detect signatures of interaction with hydrogen-free circumstellar material including a blue quasi-continuum and, uniquely, narrow oxygen emission lines that require high densities (~10^9^/cm^3^). From the observed spectra and LC, we estimate that the amount of material involved in the interaction was ~3 M_{sun}_. Our observations are in agreement with models of pulsational pair-instability SNe described in the literature.2014ApJ...785...37Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/785/37CatalogResearchIsServedByTAP VizieR generic servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)II/313 : Palomar Transient Factory (PTF) photometric catalog 1.0J/ApJ/741/97 : Light curves of Ibc supernovae (Drout+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/785/37https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/785/37http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/785/37https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/785/37https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/785/37http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/785/37GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfraredOpticaldefaultJ/ApJ/785/37/table1SN 2010mb PhotometryrecnoRecord number assigned by the VizieR team.
