The Length of Martian Crater Rays and Their Relation to Lunar Cold Spots
Trevor P. Erwin, Brandon C. Johnson, David Minton +1
Impact-generated crater rays are well-documented on the Moon, with most appearing as high-albedo streaks extending radially from a crater's center. On Mars, however, crater rays ar…
The Effects of Cuboid Particle Scattering on Reflected Light Phase Curves: Insights from Laboratory Data and Theory
Colin D. Hamill, Alexandria V. Johnson, Matt Lodge +5
Understanding the optical properties of exoplanet cloud particles is a top priority. Many cloud condensates form as nonspherical particles and their optical properties can be very…
Impacts into Titan's methane-clathrate crust as a source of atmospheric methane
Shigeru Wakita, Brandon C. Johnson, Jason M. Soderblom +5
Titan is the only icy satellite in the solar system with a dense atmosphere. This atmosphere is composed primarily of nitrogen with a few percent methane, which supports an active,…
Reflected-light Phase Curves with PICASO: A Kepler-7b Case Study
Colin D. Hamill, Alexandria V. Johnson, Natasha Batalha +4
Examining reflected light from exoplanets aids in our understanding of the scattering properties of their atmospheres and will be a primary task of future flagship space- and groun…
Light Scattering Measurements of KCl Particles as an Exoplanet Cloud Analog
Colin D. Hamill, Alexandria V. Johnson, Peter Gao
Salt clouds are predicted to be common on warm exoplanets, but their optical properties are uncertain. The Exoplanet Cloud Ensemble Scattering System (ExCESS), a new apparatus to m…
