Samal (National Central University, Taiwan) Abstract Type : Poster Abstract Category : Stars,ISM and the Galaxy Abstract : Star formation in giant molecular clouds is generally a complex interplay between the stellar feedback and the underlying cloud properties. IC 5070, a part of the giant cloud complex North American and Pelican Nebula, is one of the nearby massive star-forming regions in the Galaxy. It is located at the distance of ~ 600 pc and powered by an O5 V star. The presence of several HH objects, molecular outflows, T-Tauri stars, globules and elephant trunk-like structures pointing towards the massive star, suggests that stellar feedback is playing a key role in altering the morphology and evolution of the region. Here, we present the results of a multi-wavelength analysis based on optical photometric observations and sltiless grism Hα observations obtained with the Himalayan Chandra Telescope, infrared data from Two Micron All Sky Survey, UKIDSS, Spitzer Space Telescope, Herschel and X-ray data from Chandra Space Telescope. We detect more than 1000 young stellar candidates within the observed area (~ 30' x 30' ). The region is non-uniformly reddened with Av ranges from 3 – 20 mag. Our point source analysis is complete down to the 0.2 Msun and hence is the deepest analysis of the complex for the first time. Using multi-wavelength data sets, we analyze the physical parameters of the member stars, and various stellar aggregates, star formation history and the possible future evolution scenario of the complex will be presented. |
