Abstract:
We present a study of radial density structure of the star forming
globule, DCld303.8-14.2 (DC303), and a non-star forming globule,
Thumbprint Nebula (TPN), using near-infrared data taken with the ISAAC
instrument on the Very Large Telescope. We derive the extinction
through the globules using the color excess technique and examine the
radial density distribution using Bonnor-Ebert and power-law models.
Description:
Two globules, DC303.8-14.2 and the Thumbprint Nebula (TPN) are studied
with deep JHKs imaging. The JHKs images of the globules were obtained
during January-April 2002 with the ISAAC instrument at VLT. The JHKs
photometry of the observed fields is provided.
