Two-micron line emission from the H II region G 333.6-0.2.
Abstract
Spectrophotometry of the H II region G 333.6-0.2 with a resolution of approximately 100 shows strong emission lines of hydrogen and helium superimposed on a continuum. Spatial variations in the equivalent widths of the lines suggest the presence of very hot (at least 600 K) dust grains within the region. The shape of this very powerful H II region indicates that its dense ionized core is being continuously replenished from a reservoir of neutral gas.
