14 Dec 2008 | | Abstract: | We are engaged in a multi-wavelength study of several Galactic HII regions
that exhibit signposts of triggered star formation on their borders, and where
the collect and collapse process could be at work. When addressing the question
of triggered star formation it is critically important to ensure the real
association between the ionized gas and the neutral material observed nearby.
In this paper we stress this point, and present CO observations of the RCW 82
star forming region. The velocity distribution of the molecular gas is combined
with the study of young stellar objects (YSOs) detected in the direction of RCW
82. We discuss the YSO’s evolutionary status using near- and mid-IR data. The
spatial and velocity distributions of the molecular gas are used to discuss the
possible scenarios for the star formation around RCW 82. | | Source: | arXiv, 0812.2618 | | Services: | Forum | Review | PDF | Favorites | |
