Exploring the long-term temporal variability in polarization through multi-epoch optical spectro-polarimetry - Part II: A sample of symbiotic and red-giant stars
Arijit Maiti, Arijit Maiti. Ruchi Pandey, Ruchi Pandey +2
Measuring polarization and its temporal variability in the continuum and across emission features provides a powerful probe of the small-scale circumstellar environments of astroph…
Exploring the long-term temporal variability in polarization through multi-epoch optical spectro-polarimetry - Part I: A sample of Herbig Ae/Be and classical Be stars
Arijit Maiti, Mudit K. Srivastava
Polarization signatures across emission line features, together with their temporal evolution, offer a powerful probe of the circumstellar environments of astrophysical sources, on…
Discovery of variable polarization in H profile of symbiotic star Y Gem: A case for orbital-phase dependent variation of Raman-scattered Ly emission
Arijit Maiti, Mudit K. Srivastava, Vipin Kumar
The geometry and morphology of symbiotic stars are conducive to exhibit a variety of scattering phenomena. The prominent among them is the Raman scattering of O VI doublet 103…
A phenomenological study of the evolution of shock-induced O I emission lines in the spectrum of nova V2891 Cygni
Ruchi Pandey, Mudit K. Srivastava, Gargi Shaw
The eruption of Nova V2891 Cygni in 2019 offers a rare opportunity to explore the shock-induced processes in novae ejecta. The spectral evolution shows noticeable differences in th…
Exploring the short-term variability of H and H emissions in a sample of M dwarfs
Vipin Kumar, A. S. Rajpurohit, Mudit K. Srivastava +2
The time scales of variability in active M dwarfs can be related to their various physical parameters. Thus, it is important to understand such variability to decipher the physics…
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…
Optical and near-infrared spectroscopy of Nova V2891 Cygni: evidence for shock-induced dust formation
Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +6
We present multi-epoch optical and near-infrared observations of the highly reddened, \pion{Fe}{ii} class slow nova V2891 Cygni. The observations span 15 months since its discovery…
The Flare-Activity of 2MASSJ16111534-1757214 in the Upper Scorpius association
E. W. Guenther, D. Woeckel, P. Chaturvedi +3
Flares are known to play an important role for the evolution of the atmospheres of young planets. In order to understand the evolution of planets, it is thus important to study the…
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…
First Results from MFOSC-P : Low Resolution Optical Spectroscopy of a Sample of M dwarfs within 100 parsecs
