Late Accretion of Ceres-like Asteroids and Their Implantation into the Outer Main Belt

Driss Takir, Wladimir Neumann, Sean N. Raymond +2

Low-albedo asteroids preserve a record of the primordial solar system planetesimals and the conditions in which the solar nebula was active. However, the origin and evolution of th…

Ultraviolet Spectroscopy of Lucy Mission Targets with the Hubble Space Telescope

Oriel A. Humes, Cristina A. Thomas, Joshua P. Emery +1

The recently launched Lucy mission aims to understand the dynamical history of the Solar System by examining the Jupiter Trojans, a population of primitive asteroids co-orbital wit…

The Nature of Low-Albedo Small Bodies from 3-m Spectroscopy: One Group that Formed Within the Ammonia Snow Line and One that Formed Beyond It

Andrew S. Rivkin, Joshua P. Emery, Ellen S. Howell +9

We present evidence, via a large survey of 191 new spectra along with previously-published spectra, of a divide in the 3-m spectral properties of the low-albedo asteroid populat…

A CO2 cycle on Ariel? Radiolytic production and migration to low latitude cold traps

Richard J. Cartwright, Tom A. Nordheim, David DeColibus +11

CO2 ice is present on the trailing hemisphere of Ariel but is mostly absent from its leading hemisphere. The leading/trailing hemispherical asymmetry in the distribution of CO2 ice…

Thermophysical Investigation of Asteroid Surfaces II: Factors Influencing Grain Size

Eric M. MacLennan, Joshua P. Emery

Asteroid surfaces are subjected to mechanical weathering processes that result in the development and evolution of regolith. Two proposed mechanisms--impact bombardment and thermal…

Thermophysical Investigation of Asteroid Surfaces I: Characterization of Thermal Inertia

Eric M. MacLennan, Joshua P. Emery

The thermal inertia of an asteroid is an indicator of the thermophysical properties of the regolith and is determined by the size of grains on the surface. Previous thermophysical…
