L.K.Morgan, M.A.Thompson, J.S.Urquhart, G.J.White

TL;DR
This study uses submillimeter and infrared observations to investigate star formation in bright-rimmed clouds, revealing dense cores and early star formation stages, with different evolutionary pathways linked to cloud morphology.
Contribution
First comprehensive SCUBA survey of BRCs linking cloud morphology to star formation stages and providing evidence for triggered star formation mechanisms.
Findings
47 dense cores identified in 44 BRCs
Star formation predominantly in intermediate to high mass regimes
Different evolutionary pathways linked to BRC morphological types
Abstract
Context: Bright-rimmed clouds (BRCs) are potential examples of triggered star formation regions, in which photoionisation driven shocks caused by the expansion of HII regions induce protostellar collapse within the clouds. Aims: The main purpose of the paper is to establish the level of star formation occuring within a known set of BRCs. A secondary aim is to determine the extent, if any, to which this star formation has been promulgated by the process of photoionisation triggering. Methods:A primary set of observations is presented obtained with submillimeter SCUBA observations and archival data from near-IR and mid- to far-IR have been explored for relevant observations and incorporated where appropriate. Results:SCUBA observations show a total of 47 dense cores within the heads of 44 observed BRCs drawn from a catalogue of IRAS sources embedded within HII regions, supportive of the…
