| Abstract: |
We present BVRI photometry and medium resolution spectroscopy of the
supernova SN2007rw during ∼ 1 week to ∼ 7 months after discovery.
This supernova was classified as a type IIb event, however, based on our
analysis we suggest that SN 2007rw is a type IIL supernova. With an absolute
B magnitude of MB= -18.5 magnitude at peak, it is a bright IIL event. The
early spectrum of SN 2007rw shows Hα and Hβ with weak P-Cygni
absorption. The mass of 56Ni synthesized in the explosion is estimated as
∼ 0.43 M☉. The metallicity of the host galaxy in the supernova
region is found to be marginally subsolar. |
