Triggered Star Formation in the Orion Bright-rimmed Clouds
We have developed an empirical and effective set of criteria, based on the 2MASS colors, to select candidate classical T Tauri stars (CTTS). This provides a useful tool to study the young stellar population in star-forming regions. Here we present our analysis of the bright-rimmed clouds (BRCs) B35, B 30, IC 2118, LDN1616, LDN1634, and OrionEast to show how massive stars interact with molecular...
متن کاملTriggered Star Formation and Evolution of T-Tauri stars in and around Bright-Rimmed Clouds
The aim of this paper is to quantitatively testify the “small-scale sequential star formation” hypothesis in and around bright-rimmed clouds (BRCs). As a continuation of the recent attempt by Ogura et al. (2007, Paper I), we have carried out BV Ic photometry of four more BRC aggregates along with deeper re-observations of 2 previously observed BRCs. Again quantitative age gradients are found in...
متن کاملTriggered star formation in Bright Rimmed Clouds: The Eagle Nebula revisited
A three dimensional Smoothed Particle Hydrodynamical (SPH) model has been extended to study the radiative driven implosion effect of massive stars on the dynamical evolutions of surrounding molecular clouds. The new elements in the upgraded code are the inclusion of Lyman continuum in the incident radiation flux and the treatment of hydrogen ionisation process; introducing ionisation heating & ...
متن کاملHigh - mass star formation within the bright - rimmed cloud SFO 79
We report Radio Recombination Line (RRL) and continuum observations toward the IRAS point source 16362–4845, embedded within the Bright-Rimmed Cloud (BRC) SFO 79, a small molecular cloud lying at the edge of the HII region RCW 108. High resolution observations of the H92α hydrogen recombination line and of the continuum emission (3.6 and 6 cm) confirm the presence of a resolved Ultra Compact (U...
متن کاملA SCUBA survey of bright-rimmed clouds
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 wh...
