cds-question@unistra.frsupernovaeinfrared-photometryvisible-astronomybroad-band-photometryWe present optical photometry and spectroscopy of the Type IIP supernova SN 2004et that occurred in the nearby galaxy NGC 6946. The observations span a time range of 8541 d after explosion. The late time bolometric luminosity and the H{alpha} luminosity in the nebular phase indicate that 0.06+/-0.02M_{sun}_ of ^56^Ni was synthesized during the explosion. The plateau luminosity, its duration and the expansion velocity of the supernova at the middle of the plateau indicate an explosion energy of E_exp_=1.20^+0.38^_-0.30_x10^51^erg. The late time light curve and the evolution of the [OI] and H{alpha} emission-line profiles indicate the possibility of an early dust formation in the supernova ejecta. The luminosity of [OI] 6300, 6364{AA} doublet, before the dust formation phase, is found to be comparable to that of SN 1987A at similar epochs, implying an oxygen mass in the range 1.52M_{sun}_, and a main-sequence mass of 20M_{sun}_ for the progenitor.2006MNRAS.372.1315Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/372/1315CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/256 : Sternberg Supernova Catalogue, 2004 version (Tsvetkov+, 2004)J/A+A/317/423 : Revised photometry of SNIa (Patat, 1997)J/A+A/428/555 : UBVRIJHKs photometry of 2000cx (Sollerman+, 2004)J/AJ/112/2408 : Light Curves of 29 SNe (Hamuy+ 1996)J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/372/1315https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/372/1315http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/372/1315https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/372/1315https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/372/1315http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/372/1315GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/MNRAS/372/1315/table2Photometric observations of SN 2004ete_Umag? rms uncertainty on Umagmagstat.error;phot.mag;em.opt.UfloatnullableBmag?
