Ice in main belt asteroids and near‐Earth objects is of scientific and resource exploration interest, but small airless bodies gradually lose their ice to space by outward diffusion. Here we quantitatively estimate the time it takes a porous airless body to lose all of its interior ice, based on an analytic solution for the interior temperature field of bodies in stable orbits. Without latent heat, the average surface temperature, which is lower than the classic effective temperature, is… 
Implications for Ice Stability and Particle Ejection From High‐Resolution Temperature Modeling of Asteroid (101955) Bennu
The finding by the OSIRIS‐REx (Origins, Spectral Interpretation, Resource Identification, and Security‐Regolith Explorer) mission that its target (101955) Bennu is an active asteroid has raised
High-resolution Thermal Infrared Imaging of 3200 Phaethon
We present thermal infrared observations of the active asteroid (and Geminid meteoroid stream parent) 3200 Phaethon using the Very Large Telescope. The images, at 10.7 micron wavelength, were taken
How Many Hydrated NEOs Are There?
Hydrated minerals are tracers of early solar system history and have been proposed as a possible focus for economic activity in space. Near‐Earth objects (NEOs) are important to both of these,
Infrared Spectroscopy of Large, Low‐Albedo Asteroids: Are Ceres and Themis Archetypes or Outliers?
Low‐albedo, hydrated objects dominate the list of the largest asteroids. These objects have varied spectral shapes in the 3‐μm region, where diagnostic absorptions due to volatile species are found.
Polarimetric Decomposition of Near-Earth Asteroids Using Arecibo Radar Observations
The polarization state of radar echoes from planetary bodies contains information about the scattering mechanisms present on the surface and thus the near-surface physical properties. Polarimetric
Potential Themis Family Asteroid Contribution to the Jupiter-Family Comet Population.
It is found that dynamically evolved Themis family objects on JFC-like orbits have semimajor axes between 3.15 au and 3.40 au for the vast majority of their time on such orbits, consistent with the strong role that the 2:1 mean-motion resonance with Jupiter likely plays in their dynamical evolution.


The Lifetime of Ice on Main Belt Asteroids
We theoretically estimate the loss rate of buried ice from spherical bodies 2-3.3 AU from the Sun. The loss rate is explored as a function of about a dozen parameters. We introduce the concept of a
Crystallization, sublimation, and gas release in the interior of a porous comet nucleus
A numerical code is developed for evolutionary calculations of the thermal structure and composition of a porous comet nucleus made of water ice, in amorphous or crystalline form, other volatiles,
Internal Structure of Asteroids Having Surface Shedding due to Rotational Instability
Surface shedding of an asteroid is a failure mode where surface materials fly off due to strong centrifugal forces beyond the critical spin period, while the internal structure does not deform
New 3D thermal evolution model for icy bodies application to trans-Neptunian objects
Context. Thermal evolution models have been developed over the years to investigate the evolution of thermal properties based on the transfer of heat fluxes or transport of gas through a porous
Extensive water ice within Ceres’ aqueously altered regolith: Evidence from nuclear spectroscopy
Nuclear spectroscopy data acquired by NASA’s Dawn mission determined the concentrations of elemental hydrogen, iron, and potassium on Ceres, and show that surface materials were processed by the action of water within the interior, confirming theoretical predictions that ice can survive for billions of years just beneath the surface.
Black body temperature, orbital elements, the Milankovitch precession index, and the Seversmith psychroterms
SummaryThe temperature T of a black or gray body orbiting the Sun can be expressed in terms of spherical harmonics in latitude and longitude, its Keplerian orbital elements, and a variable describing
