New detection of near-infrared H2line emission in AFGL 5157
2003
Astronomy and Astrophysics
Narrow-band H 2 v = 1-0 S (1) and broad-band K imaging observations towards AFGL 5157 revealed a number of new H 2 knots associated with the NH 3 core in the region, implying that the multiple H 2 outflows are driven by a cluster of embedded point sources in the core. The shell around the infrared cluster is more clearly seen than before, showing a few of newly detected ridge-like features. A string of H 2 knots newly revealed along one lobe of the known CO outflow suggests a parsec-scaled jet
