Variability of Known Exoplanet Host Stars Observed by TESS
The Astronomical Journal, 2023 Both direct and indirect methods of exoplanet detection rely upon detailed knowledge of the potential host stars. Such stellar characterization allows for accurate extraction of planetary properties, as well as contributing to our overall understanding ...

A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds
Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract Field studies at terrestrial analogue sites represent an important contribution to the science of ocean worlds. The value of the science and technology investigations conducted at field analogue sites depends on the relevance of the analogue environment to the target ocean world.

Helium in the Extended Atmosphere of the Warm Superpuff TOI-1420b
The Astronomical JournalSuperpuffs are planets with exceptionally low densities ( ρ ≲ 0.1 g cm ^−3 ) and core masses ( M _c ≲ 5 M _⊕ ). Many lower-mass ( M _p ≲ 10 M _⊕ ) superpuffs are expected to be unstable to catastrophic mass loss via photoevaporation and/or boil-off ...

From Tape Reels to Global Access: A History and Future Vision of NASA's Scientific Data Management
Earth and Space Science, Volume 12, Issue 9, September 2025.Abstract Since its creation in the late 1950s, NASA has collected space science data and information that span astrophysics, Earth science, planetary science, heliophysics, and biological and physical sciences. While these data were critical to NASA's objective of expanding human knowledge of space, the early days of scientific data and information ...

Sound Velocity and Grüneisen Parameter in Shock‐Melted Silica at Deep Earth Pressures
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.Abstract Silica is a primary component of rocky planet interiors and its melt properties are important for understanding planetary formation and differentiation, magma oceans, and the deep mantle. Although well understood in the solid state, the high‐pressure behavior of liquid silica is poorly constrained at lower mantle pressures.
