This open cluster has a large number of interesting UV bright candidates. Observation of this cluster in the UV band was carried out by Ultra Violet Imaging Telescope (UVIT) onboard the ASTROSAT satellite. The UV magnitudes in one FUV (CaF2) and one NUV (B15) filter is obtained by Point Spread Function (PSF) photometry, using the DAOPHOT package in IRAF. The Colour Magnitude Diagrams (CMDs) both optical and UV - optical for this cluster is generated using the coordinate crossmatch of the the optical and UVIT photometric data. The Flexible Stellar Population Synthesis (FSPS) model is used to generate the isochrones for the optical and UVIT filters. In this study we have identified 34 UV bright objects including a Red Giant and a few Blue Straggler stars. Combining the photometric data from Two Micron All Sky Survey (2MASS) (J,H,K), Isaac Newton Telescope (INT) Photometric Hα Survey of the Northern Galactic Plane (IPHAS) (R, I) and the optical study, we have constructed Spectral Energy Distribution (SED) for 34 stars and their stellar parameters (Lʘ, Teff, Rʘ, Mʘ) have been tabulated. In an attempt to study this cluster in multiwavelength, we have found the presence of binaries. |
