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.

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 ...

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters
The Astrophysical JournalThe orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Most Super-Earths Have Less Than 3% Water
The Astrophysical JournalSuper-Earths are highly irradiated, small planets with bulk densities approximately consistent with Earth. We construct combined interior atmosphere models of super-Earths that trace the partitioning of water throughout a planet, including an iron-rich ...

Towards a Theory for the Atmospheres, Structure, and Evolution of Giant Exoplanets [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractIn this short review, I summarize some of the salient features of the emerging theory of exoplanets in general, and of giant exoplanets in particular. A focus is on the characterization of transiting planets at primary and secondary eclipse, but various other related topics are covered, if only briefly.

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 ...

CoRoT: harvest of the exoplanet program
, 2013 One of the objectives of the CoRoT mission is the search for transiting extrasolar planets using high-precision photometry, and the accurate characterization of their fundamental parameters.

The Astrophysical Journal LettersThe recent discovery of “ultrahot” ( P < 1 day) Neptunes has come as a surprise: some of these planets have managed to retain gaseous envelopes despite being close enough to their host stars to trigger strong photoevaporation and/or Roche lobe overflow ...
