cds-question@unistra.frsupernovaephotometrySome supernovae (SNe) may be powered by the interaction of the SN ejecta with a large amount of circumstellar matter (CSM). However, quantitative estimates of the CSM mass around such SNe are missing when the CSM material is optically thick. Specifically, current estimators are sensitive to uncertainties regarding the CSM density profile and the ejecta velocity. Here we outline a method to measure the mass of the optically thick CSM around such SNe. We present new visible-light and X-ray observations of SN 2010jl (PTF 10aaxf), including the first detection of an SN in the hard X-ray band using NuSTAR. The total radiated luminosity of SN 2010jl is extreme--at least 9x10^50^erg. By modeling the visible-light data, we robustly show that the mass of the circumstellar material within ~10^16^cm of the progenitor of SN 2010jl was in excess of 10M_{sun}_. This mass was likely ejected tens of years prior to the SN explosion. Our modeling suggests that the shock velocity during shock breakout was ~6000km/s, decelerating to ~2600km/s about 2yr after maximum light. Furthermore, our late-time NuSTAR and XMM spectra of the SN presumably provide the first direct measurement of SN shock velocity 2yr after the SN maximum light--measured to be in the range of 2000-4500km/s if the ions and electrons are in equilibrium, and >~2000km/s if they are not in equilibrium. This measurement is in agreement with the shock velocity predicted by our modeling of the visible-light data. Our observations also show that the average radial density distribution of the CSM roughly follows an r^-2^ law. A possible explanation for the >~10M_{sun}_ of CSM and the wind-like profile is that they are the result of multiple pulsational pair instability events prior to the SN explosion, separated from each other by years.2014ApJ...781...42Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/781/42CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/313 : Palomar Transient Factory (PTF) photometric catalog 1.0 (Ofek+, 2012)J/other/Nat/494.65 : SN 2010mc outburst before explosion (Ofek+, 2013)J/ApJ/768/47 : Swift/XRT 0.2-10keV observations of SN2009ip (Ofek+, 2013)J/ApJ/763/42 : X-ray emission from 28 SNe (Ofek+, 2013)J/AJ/144/131 : Photometry and spectroscopy of SN 2010jl (Zhang+, 2012)J/AJ/137/4517 : UVOT light curves of supernovae (Brown+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/781/42https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/781/42http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/781/42https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/781/42https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/781/42http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/781/42GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/781/42/table4Swift-XRT observationsrecnoRecord number assigned by the VizieR team.
