Abstract Type : Poster Abstract Category : Stars, ISM and Galaxy Abstract : Abstract: Young massive clusters are the most prevalent hubs of star formation activity in the Universe. Cygnus OB2 association is the closest massive young association to the Sun at a distance of ~1.4 kpc and is less hampered by extinction effects. Study of Young Stellar Objects (YSOs) in such clusters helps in understanding the evolution of low mass stars in the feedback driven environment of nearby massive stars. We present a multi-wavelength analysis of Young Stellar Objects within an area ~ 1.3 x 1.3 square degrees centred at Cygnus OB2, in optical, near-infrared and mid-infrared bands using Subaru-Hyper Suprime-Cam (HSC), United Kingdom Infrared Telescope Infrared Deep Sky Survey (UKIDSS) and Spitzer data sets. We present the classification and follow up analysis of the young stellar population in Cygnus OB2 down to brown dwarf limit. This is a premier rigorous work to analyze one of the most massive star forming regions (~(4-10)×10^4 Msun) in the Milky Way, down to very low mass-end of the Initial Mass Function (IMF). |
