- Abstract
We propose to constrain the initial stages of grain growth in early sites of star formation. This objective will be achieved by obtaining NIRSpec MSA spectroscopic observations of background stars behind three dense molecular cores of different evolutionary stages. By employing background stars, we will avoid uncertainties arising when embedded sources, with uncertain IR excesses, are used. The proposed observations will provide unprecedented spectroscopic information on the systematic variation of the extinction curve with depth into the cloud, at levels of extinction that were not possible to probe before JWST.
