Insights from Modeling Magnetar-driven Light Curves of Stripped-envelope Supernovae
Amit Kumar
This work presents the semi-analytical light curve modelling results of 11 stripped-envelope SNe (SESNe), where millisecond magnetars potentially drive their light curves. The ligh…
Signatures of the Shock Interaction as an Additional Power Source in the Nebular Spectra of SN 2023ixf
Amit Kumar, Raya Dastidar, Justyn R. Maund +2
Red supergiants may lose significant mass during the final 100-1000 years before core collapse, shaping their circumstellar environment. The supernova (SN) shockwave propagating th…
Light Curve Properties of Gamma-Ray Burst Associated Supernovae
Amit Kumar, Kaushal Sharma
A rapidly spinning, millisecond magnetar is widely considered one of the most plausible power sources for gamma-ray burst-associated supernovae (GRB-SNe). Recent studies have demon…
Unravelling the asphericities in the explosion and multi-faceted circumstellar matter of SN 2023ixf
Avinash Singh, R. S. Teja, T. J. Moriya +33
We present a detailed investigation of photometric, spectroscopic, and polarimetric observations of the Type II SN 2023ixf. Earlier studies have provided compelling evidence for a…
SN 2019nyk: A rapidly declining Type II supernova with early interaction signatures
Raya Dastidar, Giuliano Pignata, Naveen Dukiya +9
We present an optical photometric and spectroscopic analysis of the fast-declining hydrogen-rich Type II supernova (SN) 2019nyk. The light curve properties of SN 2019nyk align well…
