Journal ArticleDOI
The excitation temperature of the CH 3335-MHz line
TL;DR: In this article, the authors used the 3.3 GHz line as a proxy for H2 and obtained a wide range of excitation temperatures for nine lines of sight, including some with |Tex| < 5 K.
M20: Star Formation in a Young HII Region
TL;DR: The Trifid Nebula (M20) has a remarkable optical appearance with a large, reddish nebula of gas ionized by an O7 star (HD 164492) and trisected by obscuring dust lanes, with a blue reflection nebula in the north as mentioned in this paper.
