Their spectra shows strong hydrogen features in the early phases, followed by appearance of helium lines in late phases. The progenitors leading to such kind of explosion are not fully understood. The study of star forming regions within host galaxies can predict the possible progenitor channel of these explosions. If supernova explosion happens to be close to a star forming region, then the observation of HII knot will provide fair estimation of site metallicity. In this poster, we present progenitor properties using newly obtained narrow band H-alpha images of NGC 5806 (D ~ 25 Mpc), host to SN2012P, a type IIb event, observed from 1.3m Devasthal Fast Optical Telescope at ARIES, Nainital. The HST pre-explosion images of NGC 5806 is also available in the archive. We will also present analysis of 22 epochs of photometric observation, obtained from the 1m class telescopes at ARIES, along with 3 epochs of spectroscopic observation from other facilities. |
