Abstract
We describe an instrument under development at the University of Texas for observation of lunar occultations with complete spectral coverage from 1 - 13 μm and with limiting angular resolutions of 1 - 4 milliarcsecond over that range. The instrument will utilize three 2-D arrays that will enable spectral dispersion with a resolving power, R ~ 100, and permit pupil division to avoid blurring the Fresnel fringes of an occultation. The scientific motivation for this program is based on observations of physical properties of circumstellar disks around young, forming stars, as well as of shells around evolved stars undergoing mass loss. We also describe some examples of results with a prototype version of this instrument that has been in use at McDonald Observatory for the last 18 months.
