Exoplanet Analog Observations Of Earth From Galileo Mission Disk-integrated Photometry
The Galileo spacecraft had distant encounters with Earth in 1990 and 1992. Limited Solid State Imager (SSI) data acquired during these encounters has been previously presented, but the majority of […]

Variability in Titan’s Mesospheric HCN and Temperature Structure as Observed by ALMA
The temperature structure of Titan’s upper atmosphere exhibits large variability resulting from numerous spatially and temporally irregular external energy sources, seasonal changes, and the influence of molecular species produced via […]

Octofitter: Fast, Flexible, and Accurate Orbit Modelling to Detect Exoplanets
As next-generation imaging instruments and interferometers search for planets closer to their stars, they must contend with increasing orbital motion and longer integration times. These compounding effects make it difficult […]

Subsurface Thermophysical Properties of Europa’s Leading and Trailing Hemispheres as Revealed by ALMA
We present best-fit values of porosity — and the corresponding effective thermal inertiae — determined from three different depths in Europa’s near-subsurface (~1-20 cm). The porosity of the upper ~20 […]

Super-Earth Discovered In The Habitable Zone Of TOI-715
The discovery: A “super-Earth” ripe for further investigation orbits a small, reddish star that is, by astronomical standards, fairly close to us – only 137 light-years away. The same system […]
