No Giant Planets in the Eta Cassiopeiae System: Dynamical Implications of a Wide Binary Companion

The Astronomical Journal
Given the vast number of stars that exist within binary systems, it remains important to explore the effect of binary star environments on the formation and evolution of exoplanetary systems.

Anomalous transient enhancement of planetary ion escape at Mars

Nature Communications
Atmospheric ion escape plays a crucial role in the evolution of planetary climate and habitability. While Mars has been the focus of extensive in-situ spacecraft observations, our understanding of ion escape at Mars has been constrained by single-point ...

Inferring and Interpreting the Visual Geometric Albedo and Phase Function of Earth

The Planetary Science Journal
Understanding reflectance-related quantities for worlds enables effective comparative planetology and strengthens mission planning and execution. Measurements of these properties for Earth, especially its geometric albedo and phase function, have been ...

Influence of Orbit and Mass Constraints on Reflected Light Characterization of Directly Imaged Rocky Exoplanets

The Astrophysical Journal Letters
Survey strategies for upcoming exoplanet direct imaging missions have considered varying assumptions of prior knowledge. Precursor radial velocity surveys could have detected nearby exo-Earths and provided prior orbit and mass constraints. Alternatively,

Earth Analogs in Reflected Light: Insights from Early Spectral Characterization in Unconstrained Orbits

The Astrophysical Journal
A next generation of space-based observatories aims to detect and characterize potentially Earth-like exoplanets around Sun-like stars using reflected-light spectroscopy.
