Near-infrared survey of bright rimmed clouds
Listed in IVOA Registry (Virtual Observatory)
We conducted wide-field near-infrared imaging observations of 32 bright rimmed clouds (BRCs).
Description
Given a detection limit of 17.7mag at the K-band, we identified 2099 objects as young stellar object (YSO) candidates that displayed near-infrared excesses. Their masses, estimated from luminosities, range from 0.006M_{sun}_ to 2.7M_{sun}_.
The candidates are not uniformly distributed. For 21 BRCs, more than half of the associated YSO candidates are located inside the cloud. We found clear evidence of triggered star formation.

The number of YSO candidates is not correlated with the core mass of the molecular clouds. Instead, the YSO number increases with increasing UV photon flux from the exciting star illuminating the cloud surface. UV radiation activates star formation in the BRCs.
