cds-question@unistra.frsupernovaespectroscopyWe investigate line formation processes in Type IIb supernovae (SNe) from 100 to 500 days post-explosion using spectral synthesis calculations. The modelling identifies the nuclear burning layers and physical mechanisms that produce the major emission lines, and the diagnostic potential of these. We compare the model calculations with data on the three best observed Type IIb SNe to-date - SN 1993J, SN 2008ax, and SN 2011dh.2015A&A...573A..12Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/573/A12CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/573/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/573/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/573/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/573/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/573/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/573/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/573/A12/obsList of Meikle et al. unpublished spectra (from table1)recnoRecord number assigned by the VizieR team.
