Scientific paper

Forty-four bright-rimmed clouds associated with IRAS sources have been selected from the Palomar Sky Survey prints. They are good candidates for the sites of star formation induced by radiation-driven implosions; three well-established cases of radiation-driven implosions in bright-rimmed globules have been reported by Sugitani et al. (1989). Nine of the bright-rimmed clouds are known to be associated with molecular outflows and two (including one with an outflow) with HH objects. Most of their sizes are not more than 1 pc, similar to those of Bok globules. The luminosities of the associated IRAS sources are relatively large, about 10 to 10,000 solar luminosities, compared to those of the IRAS sources associated with dark globules or dense cores in dark cloud complexes. IRAS luminosity to cloud mass ratios are significantly greater than those in dark globules or in dense cores of dark cloud complexes.
