SLY99B - Nonequilibrium Excitation of Methanol in Galactic Molecular Clouds: Multitransitional Observations at 2 Millimeters

Short title: Slysh et al. (1999b)
Authors: Slysh, V. I. Kalenskii, S. V. Val'TTS, I. E. Golubev, V. V. Mead, K.
Journal: The Astrophysical Journal Supplement Series, Volume 123, Issue 2, pp. 515-536.

Transitions: CH3OH_132(I),CH3OH_156(II),CH3OH_157(II)

Abstract
We observed 14 methanol transitions near lambda=2 mm in Galactic star-forming regions. Broad, quasi-thermal J₀-J_-1E methanol lines near 157 GHz were detected toward 73 sources. Together with the 6_-1-5₀E and 5_-2-6_-1E lines at 133 GHz and the 7₁-7₀E line at 166 GHz, they were used to study the methanol excitation. In the majority of the observed objects, the Class I 6_-1-5₀E transition is inverted, and the Class II 5_-2-6_-1E and 6₀-6_-1E transitions are overcooled. This is exactly as predicted by models of low-gain Class I masers. The absence of the inversion of Class II transitions 5_-2-6_-1E and 6₀-6_-1E means that quasi-thermal methanol emission in all objects arises in areas without a strong radiation field, which is required for the inversion. eprintid: arXiv:astro-ph/9906090
