| Abstract: | We present photometric and spectroscopic studies of two type IIP SNe (SN 2008in and SN 2020jfo), to infer their physical parameters. These SNe exploded in the same host galaxy, M 61 (NGC 4303), at different epochs. SN 2008in was a normal Type IIP event with plateau length of ∼ 100 d and MV= –16.4 ± 0.4 mag, whereas SN 2020jfo was a short plateau (∼60 d) event with MV= –17.4 ± 0.4 mag. Hydrodynamical modeling on these events using the MESA+STELLA framework suggests that the progenitors of both the objects were Red Super Giant (RSG) stars with mass , but with different evolutionary history and environment. |
