Unraveling eMSTO in NGC 2355: Stellar Rotation and Binaries
Jayanand Maurya, Yu Zhang, Hubiao Niu
The extended Main Sequence Turn-off (eMSTO) in the open cluster NGC 2355 is investigated using precise astrometry and photometry from Gaia DR3 and spectroscopic data from the Gaia-…

The impact of stellar rotations and binaries on the shape of upper main sequence near turn off in open cluster NGC\,6067
Jayanand Maurya, Yu Zhang, Sebastian Kamann +7
We present the analysis of the extended Main Sequence Turn-Off (eMSTO) in the open cluster NGC\,6067. We derive the projected rotational velocity, \textit{v}sin\textit{i}, of the s…

Origin of extended Main Sequence Turn Off in open cluster NGC 2355
Jayanand Maurya, M. R. Samal, Louis Amard +5
The presence of extended Main Sequence Turn-Off (eMSTO) in the open clusters has been attributed to various factors, such as spread in rotation rates, binary stars, and dust-like e…
