Triggered star formation and Young Stellar Population in Bright-Rimmed Clouds
Abstract
Massive young stars play an important role in triggering the formation
of subsequent generations of stars in the Bright-Rimmed Clouds (BRCs).
We have used multiwavelength observations (optical to Far Infrared) to
identify the nearly complete census of young stellar population in a
few BRCs. Candidate Young Stellar Objects (YSOs) are identified by
Mid-IR color indices and then followed by ground based photometric
spectroscopic observations. Spectral type, effective temperature,
extinction, mass, age, mass accretion rate etc. have been determined
for individual YSOs. The spatial distribution of the YSOs and the
ionising sources for each of the BRCs have been explored using the
narrow band H-alpha images. Further the kinematics of the YSOs and the
associated OB association are also studied to understand the
triggering mechanism and timescale. We shall summarize the results of
different BRCs to explain the effect of the environment in the context
of triggered star formation scenario.
