EVLA Observations of Pluto, Charon, Makemake, Quaoar, and 2002 TC302 at 0.9 cm Wavelength

Abstract

Observations of the Trans-Neptunian Objects (TNOs) Pluto, Charon, Makemake, Quaoar, and 2002 TC302 were made with the Expanded Very Large Array at a wavelength of 0.9 cm. These observations can be used to constrain the properties of the surfaces and subsurfaces (down to ~10 cm) of these bodies, including temperature, composition, and structure. We have detected Pluto and Charon, with the emission separated on the sky; the longest wavelength detection of either of these bodies to date. We have only upper limit non-detections for Makemake and 2002 TC302, but more data remain to be reduced, and we have not reduced any Quaoar data yet.
