SN 2022xus: bridging the gap between Type IIP and IIL supernovae
Monalisa Dubey, Kuntal Misra, Naveen Dukiya +16
We present optical photometric and spectroscopic observations of the Type~II supernova SN~2022xus. The SN reached its peak {\em V} band magnitude of mag within 7 day…
SN 2023zcu: A Type IIP SN with Early Flash Features
Monalisa Dubey, Kuntal Misra, Géza Csörnyei +51
We present a detailed photometric and spectroscopic analysis of the Type IIP supernova SN~2023zcu, which exploded in the galaxy NGC~2139 (redshift = 0.006). SN~2023zcu exhibits…
What do gravitational-wave observations tell us about Luminous Red Novae?
Dhruv Jain, Shasvath J. Kapadia, Kuntal Misra +4
Luminous Red Novae (LRNe) have been argued to be related to the ejection of common envelopes (CEs) in binary star systems. Ejection of CEs leads to tightened stellar orbits capable…
Progenitor Insights of Type IIP SN 2018pq: A Comprehensive Photometric and Spectroscopic Study
Monalisa Dubey, Kuntal Misra, Raya Dastidar +10
We present high-cadence photometric and low-resolution (R 400--700) optical spectroscopic observations of Type IIP supernova, SN~2018pq, which exploded on the outskirts of t…
