Silicon monoixde: Detection of maser emission from the second vibrationally excited state
Creators
- 1. National Radio Astronomy Observatory, Green Bank, West Virginia
Description
The J = 1-0 rotational transition of the second vibrational state (v = 2) of SiO has been detected in late -type variable stars and in the center of the Orion Nebula. This transition of SiO requires 3520 K of excitation for pumping the observed maser line. The ground (v = 0) and third (v = 3) vibrational states were not detected. Subject headings: masers molecules Orion Nebula variable stars
