Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59
Astronomische Nachrichten, Volume 347, Issue 2, February 2026.ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

The Astronomical JournalThe Kepler mission enabled us to look at the intrinsic population of exoplanets within our galaxy. In period-radius space, the distribution of the intrinsic population of planets contains structure that can trace planet formation and evolution history ...

Astrometric detection of exoplanets from the ground
, 2013 Astrometry is a powerful technique to study the populations of extrasolar planets around nearby stars. It gives access to a unique parameter space and is therefore required for obtaining a comprehensive picture of the properties, abundances, and ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

The Astrophysical JournalA primary goal of characterizing exoplanet atmospheres is to constrain planetary bulk properties, such as their metallicity, C/O ratio, and intrinsic heat.

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 2, February 2026.Abstract Hot and moist “hothouse” climates occurred in Earth's past and are expected in Earth's far future climate, driven by increasing solar luminosity. In hothouse climate regimes, precipitation transitions from a quasi‐steady state, as in present‐day tropical convection, to an “episodic deluge” or relaxation‐oscillator (RO) regime where ...

Thermoelastic Contraction as a Suppressor of Atmospheric Escape in Close-in Exoplanets
The Astrophysical JournalThe survival of volatile-rich atmospheres on close-in exoplanets challenges classical escape models. We identify a fully classical, interior-driven correction: thermoelastic contraction of the planetary mantle slightly increases the gravitational binding

, 2018 Super-Earths are the most abundant planets known to date and are characterized by having sizes between that of Earth and Neptune, typical orbital periods of less than 100 days and gaseous envelopes that are often massive enough to significantly ...

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

On the Dual Nature of Atmospheric Escape
The Astrophysical JournalPlanetary atmospheres cannot remain hydrostatic at all altitudes because they approach finite density at infinite radius, implying infinite mass. Classical treatments address this in two directions: either retain a hydrostatic structure while allowing ...
