Type IIP SNe constitute about 67% of all core collapse SNe in a volume limited sample (d<30 Mpc). Thus they are the most commonly observed variety of core-collapse events. SN 2004dj is one of the brightest and nearest Type IIP supernova discovered by Nakano et al. (2004) in July 2004. It is the closest (~ 3.06 Mpc) normal type IIP supernova to date. We present extensive radio follow up observations of SN 2004dj with GMRT and VLA from 2004 to 2016. Thus we study the 12 years of evolution of this extremely bright SN. Our well sampled spectra and light curve explain properties of progenitor star, structure of the circumstellar medium etc. The extensive radio data provide unique informations about cooling mechanisms and their dominance. We interpret our results in conjunction with the previous published results based on X-ray emission from SN 2004dj. Thus we study SN2004dj in detail as a prototype of its class. |
