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…

Exploring Contact Binaries: Observational Analysis of four W Uma Binaries Using Photometry and Spectroscopy
Alaxender Panchal, Yogesh Chandra Joshi, Vishal Joshi +1
We present the multi-band photometric and low-resolution spectroscopic analysis of four W Ursae Majoris eclipsing binaries (EWs) - J080510.1+141528 (hereinafter as J0805a), J080516…

Investigating Pulsating Variables and Eclipsing Binaries in NGC 2126 using Ground and Space-based Photometry, Astrometry, Spectroscopy and Modeling
Athul Dileep, Santosh Joshi, Sneh Lata +12
Pulsating variables are prevalent in the classical δ Scuti instability strip of intermediate-age open star clusters. The cluster membership of these stars facilitates a comparativ…
