Resumen:
Bright-rimmed clouds (BRCs) are small and dense molecular clouds located
in the periphery of the evolved HII regions. The illumination of these
dark clumps by nearby OB stars might be responsible for triggered
collapse and subsequent star formation through the mechanism known as
radiation-driven implosion (RDI). We carried out a multi-wavelength
study of a BRC located in the periphery of the evolved HII region
G52.85-0.55. From the evaluation of the pressure balance between the
ionized gas located at the illuminated border of the clump and the
molecular gas, we show that shocks are being driven in the external
layers of the BRC. On the other hand the pressure balance suggests that
the birth of young stellar objects embedded in the BRC could have been
initiated by the RDI mechanism.
