SN 2018hna: 1987A-like supernova with a signature of shock breakout
Avinash Singh, D. K. Sahu, G. C. Anupama +22
High cadence ultraviolet, optical and near-infrared photometric and low-resolution spectroscopic observations of the peculiar Type II supernova (SN) 2018hna are presented. The earl…
On the observational behaviour of the highly polarized Type IIn supernova SN 2017hcc
Brajesh Kumar, Chakali Eswaraiah, Avinash Singh +10
We present the results based on photometric ( UVOT), broad-band polarimetric ( and -band) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc…
SN 2017gmr: An energetic Type II-P supernova with asymmetries
Jennifer E. Andrews, D. J. Sand, S. Valenti +77
We present high-cadence ultraviolet (UV), optical, and near-infrared (NIR) data on the luminous Type II-P supernova SN 2017gmr from hours after discovery through the first 180 days…
SN 2016B a.k.a ASASSN-16ab: a transitional type II supernova
Raya Dastidar, Kuntal Misra, Mridweeka Singh +12
We present photometry, polarimetry and spectroscopy of the Type II supernova ASASSN-16ab/SN 2016B in PGC 037392. The photometric and spectroscopic follow-up commenced about two wee…
Observational properties of a Type Ib Supernova MASTER OT J120451.50+265946.6 in NGC 4080
Mridweeka Singh, Kuntal Misra, D. K. Sahu +12
MASTER OT J120451.50+265946.6 (M12045), discovered by the MASTER Global Robotic Net, is a Type Ib supernova (SN) that exploded in NGC 4080. We present the {\it BVRI} photometric an…
