Lateral melt variations induce shift in Io’s peak tidal heating
The tidal response of Io
We compute the tidal response of Io using LOV3D27,51,62. It solves the mass, momentum, and Poisson’s equation for a self-gravitating viscoelastic body in the spectral domain using tensor spherical harmonics. Due to the…

Abundant microchondrules in 162173 Ryugu suggest a turbulent origin for primitive asteroids
Nakamura et al.11 reported similar sub-spherical objects to C-03 in Ryugu that they termed phyllosilicate nuggets and were suggested to form by aqueous alteration. The sub-spherical shapes of the sulphide-rimmed objects described here, however,…

Seasonal Changes in the Atmosphere of HD 80606 b Observed with JWST’s NIRSpec/G395H
High-eccentricity gas giant planets serve as unique laboratories for studying the thermal and chemical properties of H/He-dominated atmospheres. One of the most extreme cases is HD 80606 b—a hot Jupiter orbiting a Sun-like star with an…

Velocity Shift and Signal-to-Noise Ratio Limits for High-resolution Spectroscopy of Hot Jupiters Using Keck/KPIC
High-resolution cross-correlation spectroscopy is a technique for detecting the atmospheres of close-in planets using the change in the projected planet velocity over a few hours. To date, this technique has most often been applied to hot…

The Compositions of Rocky Planets in Close-in Orbits Tend to Be Earth-like
Hundreds of exoplanets between 1 and 1.8 times the size of Earth have been discovered on close-in orbits. However, these planets show such a diversity in densities that some appear to be made entirely of iron, while others appear to host gaseous…
