The remarkable 400 micron source NGC 6334/I/North/

Abstract

Observations at 400 microns of the NGC 6334 complex have confirmed the discovery of an unusual 1000-solar mass object, NGC 6334/I(North), which was not detected by broad-band 100-micron survey observations. The results suggest that this cool source (T = 19 + or - 5 K) is an active star formation region in a very early stage of evolution. The observed infrared luminosity of the source, 7000 solar luminosities, requires the presence of one or more embedded B stars or the formation of a dense protostellar core. Derived dust and gas densities agree well with results from molecular line observations of the complex. Nearby 100 micron peaks I and V were also observed.
