Mid-IR Spectroscopy Of Main-belt Asteroids From MIRSI At The IRTF
Abstract
Thermal emission spectra (8-13 microns) of 19 Fortuna, 4 Vesta, 1 Ceres, and several other large main-belt asteroids were measured at IRTF in 2009 and 2010. The new "MIRSI 2" (2008) interface to the Mid-Infrared Spectrometer and Imager ("MIRSI") instrument (Kassis et al. 2008, PASP 120) was used to acquire these data. The thermal emission spectra of these asteroids will be presented together with evaluations of the S/N achievable in low-resolution spectroscopy with MIRSI at IRTF. Techniques for addressing instrumental issues particular to MIRSI (Kassis et al. 2008; Sako et al. 2003, PASP 115) in the context of spectroscopic observations will also be discussed.
