Stellar rotation and binaries in open clusters with Gaia DR3

Elena Pancino, Elisabetta Reggiani, Silvia Marinoni +14

Stellar rotation is a fundamental ingredient in shaping the evolution of stars and it can also be used to trace past stellar interactions. Yet, systematic studies of stellar rotati…

AstroSat/UVIT Study of NGC 663: First detection of Be+sdOB systems in a young star cluster

Sneha Nedhath, Sharmila Rani, Annapurni Subramaniam +1

Be stars are rapidly rotating stars surrounded by a disc; however, the origin of these stars remains unclear. Mass and angular momentum transfer in close binaries account for the r…

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…
