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

The single beacon: progresses in understanding Earth as an exoplanet using DSCOVR/EPIC observations
Frontiers in Remote SensingAlmost 6000 exoplanets have thus far been confirmed, revolutionizing our understanding of planetary habitability. Yet, despite the identification of Earth-like exoplanets, definitive evidence of extraterrestrial life remains elusive.

Ion Escape From Degenerate Induced Magnetospheres: The Case of Mars
Geophysical 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−

Exoplanet interiors and habitability [PDF]
Advances in Physics: X, 2019 More than 1000 exoplanets with a radius smaller than twice that of the Earth are currently known, mainly thanks to space missions dedicated to the search of exoplanets. Mass and radius estimates, which are only available for a fraction (∼ 10%) of the exoplanets, provide an indication of the bulk composition and interior structure and show that the ...

Small Telescope Exoplanet Transit Surveys: XO
, 2017 The XO project aims at detecting transiting exoplanets around bright stars from the ground using small telescopes. The original configuration of XO (McCullough et al. 2005) has been changed and extended as described here.

Gaia Search for Stellar Companions of TESS Objects of Interest V
Astronomische 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.

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

Diversitate si Identitate Culturala in Europa, 2016 Exoplanets, discovered by Mayor and Queloz, have changed our definition of the word planet. Nowadays, nobody can defin precisely this term. Study this exemple shows that the referential sense is neither in words, nor in the head, but in a linguistic use,
