UV spectroscopy confirms SU Lyn to be a symbiotic star

Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +1

SU Lyn, a star that ostensibly appears to be an unremarkable late M type giant, has recently been proposed to be a symbiotic star largely based on its hard X-ray properties. The st…

Phase Retrieval using Single-Instance Deep Generative Prior

Kshitij Tayal, Raunak Manekar, Zhong Zhuang +4

Several deep learning methods for phase retrieval exist, but most of them fail on realistic data without precise support information. We propose a novel method based on single-inst…

Exploring the short-term variability of Hα and H\b{eta} emissions in a sample of M Dwarfs

Vipin Kumar, A. S. Rajpurohit, Mudit K. Srivastava

Activities in M dwarfs show spectroscopic variability over various time scales ranging from a few seconds to several hours. The time scales of such variability can be related to in…
