The Prevalence of Resonance Among Young, Close-in Planets

open access: yesThe Astronomical Journal
Multiple 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.

The Influence of Interior Structure and Thermal State on Impact Melt Generation Upon Large Impacts Onto Terrestrial Planets

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract We investigate the melt production of planetary impacts as a function of planet size (R/REarth $R/{R}_{\text{Earth}}$ = 0.1–1.5), impactor size (L $L$ = 1–1,000 km), and core size ratio (Rcore/R ${R}_{\text{core}}/R$ = 0.2–0.8) using a combination of parameterized convection models and fully dynamical 2D impact simulations.

Field‐Aligned Currents and Auroral Precipitation During the Terrestrial Alfvén Wing State

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract When sub‐Alfvénic (Alfvén Mach number MA< ${\mathrm{M}}_{A}< $1) plasmas impact Earth, Alfvén wings (AWs) develop. A Multiscale Atmosphere Geospace Environment simulation of the April 2023 storm, validated by Active Magnetosphere and Planetary Electrodynamics Response Experiment data, reveals the field‐aligned‐current (FAC) generation ...

Ion Escape From Degenerate Induced Magnetospheres: The Case of Mars

open access: yesGeophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract When the cone angle of the interplanetary magnetic field (IMF) becomes small, induced magnetospheres of unmagnetized planets degenerate. Using hybrid simulations, we study ionospheric ion escape in a 4° cone angle case and compare it with the nominal 55° cone angle (Parker spiral) case. The total escape rate is 1.7×1025 $1.7\times 1{0}^{25}$ s−

Disrupted Exoplanet Systems in the SuperWASP Archive [PDF]

open access: yes, 2020
The aim of this research project has been to search for disrupted or disintegrating exoplanets; this search has been carried out using archival data from the Super-WASP (Wide Angle Search for Planets) transit photometry detection programme. The main aim of the archival search was to look for objects similar to Kepler-1520b (Rappaport et al., 2012) and ...

Gaia Search for Stellar Companions of TESS Objects of Interest V

open access: yesAstronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT In this paper, we present the latest results of our ongoing multiplicity survey of (Community) TESS Objects of Interest, using astrometry and photometry from the latest data release of the ESA Gaia mission to detect stellar companions of these stars and to characterize their properties.

Architecture Classification for Extrasolar Planetary Systems

open access: yesThe Astronomical Journal
This paper presents a classification framework for the architectures of planetary systems based on a complete survey of the confirmed exoplanet population. With nearly 6000 confirmed exoplanets discovered, including more than 300 multiplanet systems with

A Microphysics Model of Multicomponent Venus' Clouds With a High‐Accuracy Condensation Scheme

open access: yesEarth and Space Science, Volume 12, Issue 6, June 2025.
Abstract Accurate modeling of the Venusian cloud structure remains challenging due to its complex microphysical properties. Condensation primarily determines the cloud particle size distribution within the various cloud layers. However, existing Venus microphysics models mainly use a full‐stationary bin scheme, which may be prone to numerical diffusion

Toward High-precision Mass Measurements of Two Sub-Neptunes in the K2-266 Planetary System Through Transit Timing

open access: yesThe Astronomical Journal
Sub-Neptunes have been found to be one of the most common types of exoplanets, yet their physical parameters and properties are poorly determined and in need of further investigation.
