Photometric study and detection of variable stars in the open clusters – I.NGC 6866

Joshi, Y. C.; Joshi, S.; Kumar, Brijesh; Mondal, S.; Balona, L. A. (2012)

We present results of a variability search in the intermediate-age open cluster NGC 6866 from 29 nights over two observing seasons. We find 28 periodic variables, of which 19 are newly identified. The periods of these ...
Photometric study of the open cluster – II. Stellar population and dynamical evolution in NGC 559

Joshi, Y. C.; Balona, L. A.; Joshi, S.; Kumar, B. (Oxford University Press, 2014)

We present UBVRI photometry of stars in the field of the intermediate-age open cluster NGC 559. By determining the stellar membership probabilities derived through a photometric and kinematic study of the cluster, we ...
Pulsation and rotation of Kepler stars in the NGC 6866 field

Balona, L. A.; Joshi, S.; Joshi, Y. C.; Sagar, R. (2013)

We present an analysis of stars in the field of the open cluster NGC 6866 (age 650 Myr) using data from the Kepler Input Catalogue (KIC) and time series photometry from the Kepler data base. We identify 31 δ Scuti and 8 γ ...
