Star Clusters in the Ultraviolet
Annapurni Subramaniam, Samyaday Choudhury, Richard de Grijs +5
Ultraviolet (UV) observations provide a powerful window into the hot and evolved stellar populations that shape the structure, evolution and integrated light of star clusters. Beca…
Unveiling the white dwarf in J191213.72-441045.1 through ultraviolet observations
Ingrid Pelisoli, Snehalata Sahu, Maxim Lyutikov +7
J191213.72-441045.1 is a binary system composed of a white dwarf and an M-dwarf in a 4.03-hour orbit. It shows emission in radio, optical, and X-ray, all modulated at the white dwa…
An HST COS ultra-violet spectroscopic survey of 311 DA white dwarfs.I. Fundamental parameters and comparative studies
Snehalata Sahu, Boris T. Gaensicke, Pier-Emmanuel Tremblay +8
White dwarf studies carry significant implications across multiple fields of astrophysics, including exoplanets, supernova explosions, and cosmological investigations. Thus, accura…
Study of blue metal-poor stars using UVIT/AstroSat
Anju Panthi, Annapurni Subramaniam, Kaushar Vaidya +5
Blue metal-poor stars are main-sequence stars that are bluer and brighter than typical turn-off stars in metal-poor globular clusters. They are thought to have either evolved throu…
Globular Cluster UVIT Legacy Survey (GlobULeS) II. Evolutionary status of hot stars in M3 and M13
Ranjan Kumar, Ananta C. Pradhan, Snehalata Sahu +4
We present a far-ultraviolet (FUV) study of hot stellar populations in the second parameter pair globular clusters (GCs) M3 and M13, as a part of the Globular cluster UVIT Legacy S…
GlobULeS-IV. UVIT/AstroSat detection of extremely low mass white dwarf companions to blue straggler stars in NGC 362
Arvind K. Dattatrey, R. K. S. Yadav, Sharmila Rani +4
We report the discovery of extremely low-mass white dwarfs (ELM WDs) as a companion of blue straggler stars (BSSs) in the Galactic globular cluster NGC 362 using images from AstroS…
