Spatially variable crater morphology on the dwarf planet Haumea

George D McDonald, Lujendra Ojha

Haumea, thought to be the Kuiper Belt's 3rd most massive object, has a fast 3.92 hr rotational period, resulting in its shape as a triaxial ellipsoid. Here, we make the first detai…

Liquid Water on Cold Exo-Earths via Basal Melting of Ice Sheets

Lujendra Ojha, Bryce Troncone, Jacob Buffo +2

Liquid water is a critical component of habitability. However, the production and stability of surficial liquid water can be challenging on planets outside the Habitable Zone and d…

Aeolian sediment transport on Io from lava-frost interactions

George D. McDonald, Joshua Méndez Harper, Lujendra Ojha +4

Surface modification on Jupiter's volcanically active moon, Io, has to date been attributed almost exclusively to lava emplacement and volcanic plume deposits. Here we demonstrate…

The sub-Neptune desert and its dependence on stellar type: Controlled by lifetime X-ray irradiation

George D. McDonald, Laura Kreidberg, Eric Lopez

Short-period sub-Neptunes with substantial volatile envelopes are among the most common type of known exoplanets. However, recent studies of the Kepler population have suggested a…

Modeling transmission windows in Titan's lower troposphere: Implications for infrared spectrometers aboard future aerial and surface missions

Paul Corlies, George D. McDonald, Alexander G. Hayes +10

From orbit, the visibility of Titan's surface is limited to a handful of narrow spectral windows in the near-infrared (near-IR), primarily from the absorption of methane gas. This…
