Observations of H2 emission from NGC 7538
- 1. Astronomy Program, SUNY-Stony Brook
Description
Observations of the molecular hydrogen emission at 2 μm in NGC 7538 are presented. A map of the ν=1-0S(1) line obtained at 24'' resolution indicates that the peak of the molecular line emission occurs between the interface of the visible H II region and the dense molecular cloud and the infrared cluster within the molecular cloud. The apparent luminosity in the S(1) line of approx.1.2L/sub sun/ is similar to that measured for Orion, approx.2.5L/sub sun/, before correction for extinction by overlying dust
