These SNe show a wide variety of light curve and spectral properties. A detailed analysis of individual SNe allows us to study the peculiarities seen in the different sub-classes of type II SNe. In this poster we present the optical observations of a type IIP SN 2014cy which occurred in the galaxy NGC 7742. High cadence photometric observations, covering a span of ~150 days, were taken with the 1.0m class telescopes at ARIES. Supplementary spectroscopic observations were taken with the 2.0m Himalayan Chandra Telescope at IAO, Hanle. The light curve evolution in different phases allows us to estimate various physical parameters such as the Ni mass, ejected mass and progenitor mass. We also present a comparison of the physical properties of a sample of other well studied type IIP SNe. |
