cds-question@unistra.frsupernovaephotometryHigh-quality collections of Type II supernova (SN) light curves are scarce because they evolve for hundreds of days, making follow-up observations time consuming and often extending over multiple observing seasons. In light of these difficulties, the diversity of SNe II is not fully understood. Here we present ultraviolet and optical photometry of 12 SNe II monitored by the Las Cumbres Observatory Global Telescope Network during 2013 to 2014, and compare them with previously studied SNe having well-sampled light curves. We explore SN II diversity by searching for correlations between the slope of the linear light-curve decay after maximum light (historically used to divide SNe II into IIL and IIP) and other measured physical properties. While SNe IIL are found to be on average more luminous than SNe IIP, SNe IIL do not appear to synthesize more ^56^Ni than SNe IIP. Finally, optical nebular spectra obtained for several SNe in our sample are found to be consistent with models of red supergiant progenitors in the 12-16M_{sun}_ range. Consequently, SNe IIL appear not to account for the deficit of massive red supergiants as SN II progenitors.2016MNRAS.459.3939Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/459/3939CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/459/3939https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/459/3939http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/459/3939https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/459/3939https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/459/3939http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/459/3939GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/459/3939/table2 (SNe type II)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/459/3939/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/459/3939/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/459/3939/table2?GETtext/xml+votable180.050000true94.0764583-21.37580560.0055555555555555566/37 611 664 2262 3861 4410 4490 5629 5715 6037 7386 8256 8359 9658 10991 11027 12706 12758 13435 13522 13903 14754 15592-15593 17594 18296 18398 18795 18895 18913 19536 19584 19614 19627 19710 20060 20865 20875 21148 21198 22613 22751 23827 24915 25079 25153 25279 25438 25645 25742 26191 26234 26303 26433 26914 27514-27515 27643 27840 28033 28167 29348 30038 30194 31107 32960 33121 33131 33146 33228 33335 33425 33427 33795 33904 33958 34361 34777 35993 36210 36377 36489 36785 36789 36799 36908 37582 38350 38786 38956 39108 40267 40659 40819 42025 43233 43325 43473 44726 46041 46082-46083 46512 47187 47460 48661 48665 48667https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/459/3939?format=asciiOpticaldefaultJ/MNRAS/459/3939/table2SNe type IISimbadNameSimbad column added by the CDSmeta.idcharNameSN namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
