| Abstract : | We present spectroscopic and photometric observations of the Type IIP supernova, SN~2020jfo, in UV and optical wavelengths. SN~2020jfo occurred in the spiral galaxy M61 (NGC\,4303), with eight observed supernovae in the past 100 years. SN~2020jfo exhibited a short plateau lasting $58\pm2$\,d, putting it under a few rare short plateau events. SN~2020jfo achieved a maximum brightness in \emph{V}-band of $\rm M_V=-17.4\pm0.4$\,mag at about $\rm 7.7\pm0.5$\,d since explosion. From the bolometric light curve, we have estimated the mass of $\rm ^{56}Ni$ synthesised in the explosion to be $\rm 0.033\pm0.006\,M_\odot$. The observed spectral features are typical for a type IIP supernova except for shallow H$\alpha$ absorption throughout the evolution and the presence of stable $\rm ^{58}$Ni feature at 7378\,\AA, in the nebular phase. Using hydrodynamical modelling in the \texttt{MESA\,+\,STELLA} framework, we have tried to constrain some of the progenitor properties. |
