Abstract:
We present the results of a near-infrared survey of the young stellar
cluster associated with the IRAS 16571-4029 source.
The main purpose of this survey is to study the cluster members and
find the ionizing sources of the associated HII region.
Description:
The stellar population was studied by using color-color and
color-magnitude diagrams, as well as by analysing the spectral energy
distributions in the near- and mid-infrared wavelengths. The extended
emission was studied by the construction of contour diagrams, which
were compared with near- and mid-infrared images. We computed the
corresponding number of Lyman continuum photons (using the integrated
Brγ flux density) and compared it with that obtained from the
5GHz flux density to derive a mean visual extinction.
The NIR images were taken in the 2004 May observing run, using the
Near Infrared Camera (CamIV) of the Laboratorio Nacional de
Astrofisica, Brazil, which is based on a Hawaii 1024x1024
HgCdTe detector, attached to the 1.6m Perkin-Elmer telescope.
