Title: Optical/infrared ancillary photometry of young stars for the Herschell Key Project GASPS
Abstract:
This proposal aims at using the queue-mode 1.3m telescope at CTIO to
gather near-contemporaneous photometric measurements of a sample of
objects that will be observed with the Herschel Space Observatory in the
upcoming months as part of the Open Time Key Program GASPS. This
project is aimed at characterizing the gas content of circumstellar
disks around young stars throughout the planet formation phase. In
order to model the Herschel data in a coherent manner, it is necessary
to determine each star's basic properties (effective temperature, mass,
luminosity), which implies obtaining a complete broadband spectral
energy distribution to combine with existing longer data (AKARI,
Spitzer, Herschel and millimeter single-dish and interferometric
fluxes). Here we propose to obtain new simultaneous optical and IR
photometric measurements of 112 targets that cannot be observed from
Northern observatories. In addition to provide a sound basis for our
disk modeling effort, the observations proposed here will also offer new
insight on the location, morphology and evolution of the disks' inner
rim in conjunction with the upcoming AKARI data.
