Deep researches of SNe associated with long-GRBs have been confirmed after 1997. It is very interesting to note that first three pairs of GRBs and supernova those are observed to be connected (1.GRB 980425- SN1998bw, 2. GRB 030329- SN2003dh, 3. GRB 031203- SN2003lw) have all three type Ic BL SNe. Also, H-stripped super luminous supernovae (SLSNe-I) are identified by their observed high peak luminosity. These SNe can be distinguished from normal-luminosity SNe solely from their spectra over a wide range of light-curve phases. From the list of all SLSNe, we have analyzed photo-metric data of those SNe having light curves in UBVRI/ugriz bands. By fitting different models on the bolometric light curves, we have find out different parameters and possible progenitor of these SNe. We have also analyzed spectroscopic data of this sample of SLSNe by fitting SYN++ which allows us tracing the evolution of layers expansion in detail. We tentatively group objects by how well they match either SN 2011ke or PTF12dam and discuss the possibility that physically distinct events may have been previously grouped together under the SLSN-I label. By doing all this study we got a lot of information about the progenitors, physical mechanism and environment of these events. |
