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…

Insights into the 3D layered structure of nearby open clusters through N-body simulations
Kaixiang Lang, Yu Zhang, Hubiao Niu +3
Context. Open clusters (OCs) are important for understanding star formation, dynamics, and evolution. Previous studies have indicated a relationship between cluster structure and m…
