A rotation-based census of blue lurker candidates in open clusters
Vikrant V. Jadhav, Khushboo K. Rao, Elisabetta Reggiani
Blue lurkers (BLs) are rejuvenated main-sequence stars hidden among normal main-sequence stars on color-magnitude diagrams of star clusters. In comparison, the blue straggler stars…
Discovery of a barium blue straggler star in M67 and sighting of its WD companion*
Harshit Pal, Annapurni Subramaniam, Arumalla B. S. Reddy +1
We report the discovery of a barium blue straggler star (BSS) in M67, exhibiting enhancements in slow neutron-capture (-) process elements. Spectroscopic analysis of two BSSs (W…
UOCS. XIV. Uncovering extremely low mass white dwarfs and blue lurkers in NGC 752
Vikrant V. Jadhav, Annapurni Subramaniam, Ram Sagar
Evolutionary pathways of binary systems are vastly different from single stellar evolution, and thus, there is a need to quantify their frequency and diversity. Open clusters are t…
UOCS-XI. Study of blue straggler stars in open cluster NGC 7142 using UVIT/AstroSat
Anju Panthi, Kaushar Vaidya, Nagaraj Vernekar +3
We present a study of blue straggler stars (BSSs) of open cluster NGC 7142 using AstroSat/UVIT data and other archival data. Using a machine learning-based algorithm, ML-MOC, on Ga…
Field blue straggler stars: Discovery of white dwarf companions to blue metal-poor stars using UVIT/AstroSat
Anju Panthi, Annapurni Subramaniam, Kaushar Vaidya +4
Blue metal-poor (BMP) stars are the main-sequence stars that appear bluer and more luminous than normal turn-off stars of metal-poor globular clusters. They are believed to be eith…
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…
