Abstract:
We present high-resolution near-infrared imaging of the compact HII
region N159-5 and its immediate environment in the giant-star forming
region N159 in the LMC. N159-5 was observed at high spatial resolution
0.11"-0.25" in the K-band using the ESO Very Large Telescope UT4
(VLT), equipped with the NAOS adaptive optics system. Our data reveal
that N159-5 has a complex morphology formed mainly by two wings and
probably a single central bright star, embedded in diffuse emission of
4.5" diameter. A remarkable embedded tight cluster of approximatively
the same size, containing at least 38 faint stars coinciding with
N159-5, is also detected. Such clusters can be found in galactic HII
regions like the star-forming regions SH2 269 or M42. At the location
of the radio peak, especially in the bright western wing, this cluster
is rich in stars. Spectroscopic observations reveal that the diffuse
region is constituted mainly of dust continuum and that the bright
star #2-55 could be of type O8 V. A comparison with the radio
observation flux of N159-5 published in the literature seems to show
that the bright star #2-55 is not the only ionization source
of N159-5. Towards N159-5 molecular H_2_ emission is detected. A model
of the region is proposed.
Description:
NIR observations of N159-5 were obtained at the ESO-VLT during October
and December 2004. Images and spectra were obtained using NACO
composed of the Nasmyth Adaptative Optics System (NAOS) and the High
Resolution IR Camera and Spectrometer (CONICA).
The table dipslays the results of a DAOPHOT/NSTAR run on VLT/NACO
images of N159-5 in the LMC obtained with the S54 and S27 camera of
0.05273"/pix and 0.02637"/pix.
