The carbon star DY Persei may be a cool R Coronae Borealis variable
D. A. Garcia-Hernandez, N. Kameswara Rao, D. L. Lambert +3
Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric surveys of the Galaxy an…
UOCS-IX. AstroSat/UVIT study of the open cluster NGC 2818: Blue Stragglers, Yellow Stragglers, Planetary Nebula, and their membership
Sharmila Rani, Gajendra Pandey, Annapurni Subramaniam +1
We present the first far-UV (FUV) imaging results of the intermediate-age Galactic open cluster NGC 2818 that has a Planetary nebula (PN) within the field using images taken from t…
Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21
We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…
AstroSat study of the globular cluster NGC 2298: probable evolutionary scenarios of hot HB stars
Sharmila Rani, Gajendra Pandey, Annapurni Subramaniam +3
We present the far-UV (FUV) photometry of images acquired with UVIT on AstroSat to probe the horizontal branch (HB) population of the Galactic globular cluster NGC 2298. UV-optical…
Study of UV bright stellar populations in the globular cluster NGC 1261 using AstroSat
Sharmila Rani, Gajendra Pandey, Annapurni Subramaniam +2
We present the UV photometry of the globular cluster NGC 1261 using images acquired with the Ultraviolet Imaging Telescope (UVIT) on-board ASTROSAT. We performed PSF photometry on…
Detection of a White Dwarf companion to a Blue Straggler Star in the outskirts of globular cluster NGC 5466 with the Ultraviolet Imaging Telescope (UVIT)
Snehalata Sahu, Annapurni Subramaniam, Mirko Simunovic +8
We report the discovery of a hot white dwarf (WD) companion to a blue straggler star (BSS) in the globular cluster (GC) NGC 5466, based on observations from the Ultra-Violet Imagin…
