UOCS VII. Blue Straggler Populations of Open Cluster NGC 7789 with UVIT/AstroSat
Kaushar Vaidya, Anju Panthi, Manan Agarwal +4
NGC 7789 is a 1.6 Gyr old, populous open cluster located at 2000 pc. We characterize the blue straggler stars (BSS) of this cluster using the Ultraviolet (UV) data from…
UOCS.VI. UVIT/AstroSat detection of low-mass white dwarf companions to 4 more blue stragglers in M67
Sindhu Pandey, Annapurni Subramaniam, Vikrant Jadhav
Blue stragglers stars (BSSs) in M67 have attracted attention from observations and theory to unravel their formation mechanisms. In the series of Ultra Violet Imaging Telescope (UV…
UOCS. IV. Discovery of diverse hot companions to blue stragglers in the old open cluster King 2
Vikrant V. Jadhav, Sindhu Pandey, Annapurni Subramaniam +1
King 2, one of the oldest clusters in the Milky Way, with an age of 6 Gyr and distance of pc, has been observed with UVIT payload on the \textit{ASTROSAT}. With…
PKS1830-211: OH and HI at z=0.89 and the first MeerKAT UHF spectrum
F. Combes, N. Gupta, S. Muller +20
The Large Survey Project (LSP) "MeerKAT Absorption Line Survey" (MALS) is a blind HI 21-cm and OH 18-cm absorption line survey in the L- and UHF-bands, with the primary goal to bet…
UOCS. V. UV study of the old open cluster NGC 188 using AstroSat
Sharmila Rani, Annapurni Subramaniam, Sindhu Pandey +3
We present the UV photometry of the old open cluster NGC188 obtained using images acquired with Ultraviolet Imaging Telescope (UVIT) on board the ASTROSAT satellite, in two far-UV…
UVIT/ASTROSAT studies of Blue Straggler stars and post-mass transfer systems in star clusters: Detection of one more blue lurker in M67
Annapurni Subramaniam, Sindhu Pandey, Vikrant V. Jadhav +1
The blue straggler stars (BSSs) are main-sequence (MS) stars, which have evaded stellar evolution by acquiring mass while on the MS. The detection of extremely low mass (ELM) white…
