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…
Globular Clusters UVIT Legacy Survey (GlobULeS) I. FUV-optical Color-Magnitude Diagrams for Eight Globular Clusters
Snehalata Sahu, Annapurni Subramaniam, Gaurav Singh +22
We present the first results of eight Globular Clusters (GCs) from the AstroSat/UVIT Legacy Survey program GlobULeS based on the observations carried out in two FUV filters (F148W…
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…
Nigraha: Machine-learning based pipeline to identify and evaluate planet candidates from TESS
Sriram Rao, Ashish Mahabal, Niyanth Rao +1
The Transiting Exoplanet Survey Satellite (TESS) has now been operational for a little over two years, covering the Northern and the Southern hemispheres once. The TESS team proces…
