SN 2017hcc and SN 2023usc a comparative spectroscopic study of type IIn supernovae
Sethulakshmi Vazhayil, Firoza K. Sutaria, Riddhiman Sharma +1
We report on a spectroscopic study of the bright, nearby type-IIn supernova SN 2017hcc, and SN 2023usc using data obtained from the Himalayan Chandra Telescope (HCT). SN 2017hcc is…
Planetary Nebulae with UVIT: A Progress Report
N. Kameswara Rao, Sutaria F., Murthy J. +2
The spectral region between 1250 Angstroms - 3000 Angstroms contains important spectral lines to understand the morphological structures and evolution of planetary nebulae. This is…
Type IIP Supernova Progenitors III: Blue to Red Supergiant Ratio in Low Metallicity Models with Convective Overshoot
Gururaj A. Wagle, Alak Ray, Adarsh Raghu
The distribution of stars in the Hertzsprung Russell diagram (HRD) for a stellar conglomeration represents a snapshot of its evolving stellar population. Some of the supergiant sta…
Type IIP Supernova Progenitors II: Stellar Mass and Obscuration by the Dust in the Circumstellar Medium
Gururaj A. Wagle, Alak Ray
It has been well established from a variety of observations that red supergiants (RSGs) loose a lot of mass in stellar wind. Dust formed in this emitted gas over a few decades befo…
Type IIP Supernova Progenitors and their explodability I: Convective Overshoot, Blue Loops and Surface Composition
Gururaj A. Wagle, Alak Ray, Ajay Dev +1
We present the evolution of massive star progenitors of supernovae of type IIP. We take the example of the nearby and well-studied SN 2013ej. We explore how convective overshoot af…
Type Ib supernova Master OT J120451.50+265946.6: radio emitting shock with inhomogeneities crossing through a dense shell
Poonam Chandra, A. J. Nayana, Claes-Ingvar Bjornsson +4
We present radio observations of a Type Ib supernova (SN) Master OT J120451.50+265946.6. Our low frequency Giant Metrewave Radio Telescope (GMRT) data taken when the SN was in the…
