Neon II 12.8 Microns Emission from the Galactic Center and Compact Hydrogen II Regions.
Abstract
A tandem scanning Fabry-Perot interferometer and a 3M telescope were used to observe the Ne II fine-structure emission line from the galactic center and several compact H II regions. The compact H II region G333.6-0.2 was studied by comparing the predictions of a model with the observed thermal radio continuum, Ne II (12.8 micron) emission, S III (18.7 micron) emission and infrared continuum. The central brightness of Ne II emission from three other compact H II regions (G268.0-1.1, G291.3-0.7 and G298.2-0.3) was measured. Doppler velocities of the Ne II emission from the galactic center range from about +200 km/s to -350 km/s with respect to the local standard of rest.
