Title: Edge-on Disks Around the Youngest Protostars
Abstract:
We propose high-resolution imaging in the mid-infrared (L'-band) of nearby,
nearly edge-on, Class 0 protostars (D < 300 pc). The nearly edge-on
inclination of these protostars, as inferred from Spitzer observations, makes
these a unique sample for studying the properties of nascent disks in very
young protostars. These observations will complement existing sub-mm
interferometry of disks by providing constraints on the vertical and radial
structure of disks and tracing more extended/tenuous disk material in both
the radial and vertical directions. By using Monte Carlo radiative transfer
models to simultaneously model the subm-mm and L'-band data, we can constrain
the physical parameters needed to understand the early evolution of these
disks. These observations will extend existing HST studies of edge-on disks
around more evolved objects by using the longer-wavelength capabilities of
Gemini to penetrate the obscuration around the youngest protostars and
resolve their disks.
