Magnetic Evolution of Super‐Earth Exoplanets With a Basal Magma Ocean
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Habitability of super‐Earths likely requires self‐sustained magnetic fields to shield their atmospheres from stellar forcing. Extreme pressures and temperatures probably produce a long‐lived basal magma ocean (BMO), a potential source for these fields.

The Astrophysical Journal LettersDetections of long-period giant exoplanets will expand dramatically with Gaia Data Release 4, but interpreting these signals will require care. We derive the astrometric resoeccentric degeneracy: an astrometric analogue of the well-known radial velocity ...

The Astronomical JournalThe degree of alignment between a star’s spin axis and the orbital plane of its planets (the stellar obliquity) is related to interesting and poorly understood processes that occur during planet formation and evolution.

EXOPLANET DETECTION METHODS: AN OVERVIEW OF TECHNIQUES AND LIMITATIONS
Kosmìčna nauka ì tehnologìâThis article provides an overview of the main methods used in the search for exoplanets, including the transit method, radial velocity, astrometry, and direct imaging. Through the analysis of various sources, the applicability, strengths, and inherent limitations of each technique are assessed. The transit method, responsible for approximately 75 % of

A radiometric model for demonstration of exoplanets detection by the transit method
Physics EducationAbstract This work describes an exact radiometric model for experimental demonstrators of the detection of exoplanets by the transit method. This model generalises the calculation of the depth of occultation from the standard transit method to the case of a finite size demonstrator apparatus.

The Astronomical JournalGaia astrometry of nearby stars is precise enough to detect the tiny displacements induced by substellar companions, but radial velocity (RV) data are needed for definitive confirmation.

The GPU phase folding and deep learning method for detecting exoplanet transits
Monthly Notices of the Royal Astronomical SocietyABSTRACT This paper presents GPFC, a novel Graphics Processing Unit (GPU) Phase Folding and Convolutional Neural Network (CNN) system to detect exoplanets using the transit method. We devise a fast-folding algorithm parallelized on a GPU to amplify low signal-to-noise ratio transit signals, allowing a search at high precision and speed ...
