The Prevalence of Resonance Among Young, Close-in Planets
The Astronomical JournalMultiple planets undergoing disk migration may be captured into a chain of mean-motion resonances with the innermost planet parked near the disk’s inner edge.

UniverseThe distribution of period ratios for 580 known two-planet systems is apparently nonuniform, with several sharp peaks and troughs. In particular, the vicinity of the 2:1 commensurability seems to have a deficit of systems.

On homogeneous statistical distributions exoplanets for their dynamic parameters
, 2009 Correct distributions of extrasolar systems for their orbital parameters (semi-major axes, period, eccentricity) and physical characteristics (mass, spectral type of parent star) are received. Orbital resonances in extrasolar systems are considered. It is shown, that the account of more thin effects, including with use of wavelet methods, in obviously ...

Detectors and cooling technology for direct spectroscopic biosignature characterization
, 2016 Direct spectroscopic biosignature characterization (hereafter "biosignature characterization") will be a major focus for future space observatories equipped with coronagraphs or starshades.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.Abstract Parameterizing radiative transfer in climate models means navigating trade‐offs between physical accuracy and conceptual clarity. However, currently available schemes sit at the extremes of this spectrum: correlated‐k schemes are fast and accurate but rely on lookup tables which obscure the underlying physics and make such schemes difficult to

Investigating the Origins of Hot Neptunes from Radial Velocity Data
The Astronomical JournalHot Neptunes are extrasolar planets that are similar in size to Neptune in our solar system but are much closer to their host stars, completing an orbit in 10 days or less. The origin of hot Neptunes is not fully understood.

Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA)
, 2017 When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-

Sustainable Water Systems in Space: A Review of Current Technologies and Future Prospects
Water Resources Research, Volume 62, Issue 2, February 2026.Abstract Sustainable water management is a critical challenge in space exploration, where the limited availability of resources requires innovative approaches to ensure astronauts' survival on long‐duration missions. This narrative review explores the key technologies and methods involved in water recycling, in situ resource utilization (ISRU), and ...
