Ohmic Dissipation During the Formation of Super-Earth

The Astrophysical Journal, 2023
The super-Earth population, as one of the representatives of exoplanets, plays an important role in constraining the planet formation theories. According to the prediction from core-accretion models, super-Earths should be rare because their masses are ...

Exoplanet Predictions Based on Harmonic Orbit Resonances

, 2017
The current exoplanet database includes 5454 confirmed planets and candidate planets observed with the KEPLER mission. We find 932 planet pairs from which we extract distance and orbital period ratios.

High resolution imaging with Fresnel interferometric arrays: suitability for exoplanet detection [PDF]

, 2005
We propose a new kind of interferometric array that yields images of high dynamic range and large field. The numerous individual apertures in this array form a pattern related to a Fresnel zone plate. This array can be used for astrophysical imaging over

A Cross‐Correlation Method to Evaluate Wind Retrieval Accuracy on Mars Using Simulated Microwave Limb Sounder Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract While aspects such as the temperature and composition of the Martian atmosphere are relatively well known thanks to observations from numerous space missions, Martian atmospheric dynamics remain poorly constrained due to the scarcity of direct wind measurements. The use of microwave limb sounders to retrieve winds has been proposed in the past,

Formation of Close-in Neptunes around Low-mass Stars through Breaking Resonant Chains

The Astrophysical Journal
Conventional planet formation theories predict a paucity of massive planets around small stars, especially very low-mass (0.1−0.3 M _⊙ ) mid-to-late M dwarfs. Such tiny stars are expected to form planets of terrestrial sizes but not much bigger. However,

A Unified Treatment of Kepler Occurrence to Trace Planet Evolution. I. Methodology

The Astronomical Journal, 2023
We present Kepler exoplanet occurrence rates for planets between 0.5 and 16 R _⊕ and between 1 and 400 days. To measure occurrence, we use a nonparametric method via a kernel density estimator and use bootstrap random sampling for uncertainty estimation.

Formation of Asteroid (16) Psyche by a Giant Impact

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

Investigating the Origins of Hot Neptunes from Radial Velocity Data

The Astronomical Journal
Hot 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.

Highly Sensitive Adaptive Protection for EV‐Integrated Distribution Networks

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
Integrating electric vehicle (EV)‐charging infrastructure presents environmental advantages, particularly in curbing carbon emissions within the transport sector and promoting sustainable energy solutions. However, the ascending adoption of EVs transforms the operational dynamics of low‐voltage distribution networks by introducing bidirectional power ...

Directly Imaging Rocky Planets from the Ground [PDF]

, 2019
Over the past three decades instruments on the ground and in space have discovered thousands of planets outside the solar system. These observations have given rise to an astonishingly detailed picture of the demographics of short-period planets, but are
