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…
