Description
Stripped-envelope (Type IIb and Ib/c) supernovae form a special group within core-collapse SNe because their progenitor lost a significant amount of the H and He layers during the pre-supernova evolution. And as far as we know, there are some discrepancies between the physical parameters derived from their early- and late-time light curve models. Moreover, most of these events show a peculiar slope in the late time that can not be explained only by the radioactive decay of Ni and Co. One possibility to solve this issue is the gamma-ray and positron trapping, which plays an important role in forming the shape of the late-time light curve of SESNe. Or it is also possible that this effect is due to titanium decay, which can be taken into account besides nickel and cobalt decay.
