ALMA Band-7 Flux Density Prediction of the Haumea Ring System for Ongoing Observations

Abstract

Abstract In 2017, multi-chord occultation observations found a ring around the dwarf planet (136108) Haumea, and provided direct measurements of the size and an estimate of the apparent opacity of the ring system. Based on these properties, Müller et al. estimated the thermal contribution of Haumea’s ring at 20–500 μm. Here, we predict the flux densities of the ring of Haumea at ∼870 μm for ongoing measurements with ALMA.
