Triggered 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 کاملTriggered 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 کاملEmbedded Star Formation in the Eagle Nebula
M16=NGC 6611, the Eagle Nebula, is a well studied region of star formation and the source of a widely recognized Hubble Space Telescope (HST) image. High spatial resolution infrared observations with the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) on HST reveal the detailed morphology of two embedded star formation regions that are heavily obscured at optical wavelengths. It is ...
متن کاملStar Formation in the Eagle Nebula
M16 (the Eagle Nebula) is a striking star forming region, with a complex morphology of gas and dust sculpted by the massive stars in NGC 6611. Detailed studies of the famous “elephant trunks” dramatically increased our understanding of the massive star feedback into the parent molecular cloud. A rich young stellar population (2−3 Myr) has been identified, from massive O-stars down to substellar...
