Investigating Anomalous Flux from the Asteroids (511) Davida and (423) Diotima

Abstract

Asteroids are important tracers of the evolutionary history of our solar system. Historically, observations of asteroids in the millimeter have revealed a deficit of flux compared to expectations from the IR. This deficit is thought to relate to the material properties of the asteroid regolith. Recently, the Atacama Cosmology Telescope reported excess millimeter flux from two asteroids, (511) Davida and (423) Diotima. This excess flux is difficult to explain in the standard framework of asteroid thermal emission. We propose observations with MUSTANG-2 and Ka band, including full light curves with Ka band, to help resolve this mystery.
