Optical observations of supernova 2012aw

Bose, S; Kumar, B; Sutaria, F. K; Roy, Rupak; Kumar, B; Bhatt, V. K; Chakraborti, S (Cambridge University Press, 2014-01)

We present optical UBVRI photometric and low-resolution spectroscopic follow-up observations of a type II SN 2012aw in a nearby (~10 Mpc) galaxy M95 during 4 to 270 days post-explosion. The evolution characteristics of ...
The optical photometric and spectroscopic investigation of type IIP supernova 2012A

Roy, R; Sutaria, F. K; Bose, S; Johnson, S; Dwarkadas, V; York, B; Kumar, B; Kumar, B; Bhatt, V. K; Chakraborti, S; York, D; Ritchey, A; Saurage, G; Kaiser, M B (Cambridge University Press, 2014-01)

Supernova 2012A was discovered on 7.39UT, January, 2012 in the nearby galaxy NGC 3239 at an unfiltered magnitude of 14.6 and classified spectroscopically as a Type IIP event. Here, we present the optical photometric and ...
Supernova 2012aw – a high-energy clone of archetypal Type IIP SN 1999em

Bose, Subhash; Kumar, Brijesh; Sutaria, F. K; Kumar, Brajesh; Roy, Rupak; Bhatt, V. K; Pandey, S. B; Chandola, H. C; Sagar, R; Misra, Kuntal; Chakraborti, Sayan (Oxford University Press, 2013-08-11)

We present densely sampled UBVRI/griz photometric and low-resolution (6–10 Å) optical spectroscopic observations from 4 to 270 d after explosion of a newly discovered Type II SN 2012aw in a nearby (∼9.9 Mpc) galaxy M95. ...
