Title: Multi-color interferometric investigations of YSO disks
Abstract:
We propose to study inner circumstellar disks of YSOs with the CHARA
array using H- and K-band science instruments. The primary objective is
to resolve and characterize the inner dust and gas disks in order to
test disk models of Pre-Main Sequence (PMS) stars, and establish density
and temperature profiles in the inner disks. The proposed CHARA
observations would provide complementary measurements to our ongoing YSO
study with the Keck Interferometer using the N-band Nuller, L-band and K-
band science instruments. These studies have broad implications in
understanding physical processes such as dust condensation, accretion
and mass loss. The CHARA array is uniquely capable of making the
proposed measurements, owing to larger and multiple baseline choices.
