Optical Spectroscopy and Temporal Evolution of the Nova V1405 Cas
Gesesew R. Habtie, Ramkrishna Das, Elias Aydi +1
This paper presents the findings from our study of nova V1405~Cas over the first 1051 days after the outburst. The study includes an analysis of the photometric light curve evoluti…
Fate and detectability of rare gas hydride ions in nova ejecta: A case study with nova templates
Milan Sil, Ankan Das, Ramkrishna Das +6
HeH was the first heteronuclear molecule to form in the metal-free Universe after the Big Bang. The molecule gained significant attention following its first circumstellar dete…
Spectroscopic study of the Quiescent Stages in between the 2006 and 2021 outbursts of RS Ophiuchi
Gesesew R. Habtie, Ramkrishna Das
This paper presents a comprehensive spectroscopic analysis of the quiescent stage of the recurrent nova RS Ophiuchi between its 2006 and 2021 outbursts. The spectra shows prominent…
Study of the fastest classical nova, V1674 Her: Photoionization and Morpho-kinemetic model analysis
Gesesew R. Habtie, Ramkrishna Das, Ruchi Pandey +2
We present the results of the investigation of the nova V1674 Her (2021), recognised as the swiftest classical nova, with days. The distance to the nova is estimate…
Near-infrared spectroscopic and photometric evolution of Nova V476 Scuti -- a nova that formed optically thin dust
R. K. Das, D. P. K. Banerjee, N. M. Ashok +1
We present results of near-infrared (near-IR) (1.07 - 2.5 m) spectroscopic and photometric observations of Nova V476 Scuti (V476 Sct) which was discovered in outburst in 2…
Near-infrared studies of the 2010 outburst of the recurrent nova U Scorpii
D. P. K. Banerjee, R. K. Das, N. M. Ashok +6
We present near-IR observations of the 2010 outburst of U Sco. JHK photometry is presented on ten consecutive days starting from 0.59 days after outburst. Such photometry can gainf…
