Indian Institute of Astrophysics Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : Supernova ASASSN14dq was discovered at a V-band magnitude of ~15.7 on July 08, 2014 in the dwarf galaxy UGC 11860(z~ 0.010424) at approximately 9" from the galactic center and was classified initially as a Type II supernova. The supernova was monitored in the optical wavelengths using the HFOSC instrument installed at the 2.0m Himalayan Chandra Telescope(HCT). The observations were done at 38 epochs spanning a period of over 6 months ranging from July 15, 2014 to Jan 25, 2015. The UBVRI broad-band photometric and low-resolution spectroscopic data were used to study the light curve and spectroscopic evolution of the supernova. The explosion parameters such as the photospheric temperature, the peak absolute magnitude, Ni-56 mass, kinetic energy of the ejecta were estimated based on the parametric fits to the light curve and the modelling of the spectra using SYNOW. Also presented is a discussion on the progenitor mass and the supernova environment. |
