Dynamics of the tachocline
Antoine Strugarek, Bernadett Belucz, Allan Sacha Brun +2
The solar tachocline is an internal region of the Sun possessing strong radial and latitudinal shears straddling the base of the convective envelope. Based on helioseismic inversio…
On Earth's habitability over the Sun's main-sequence history: joint influence of space weather and Earth's magnetic field evolution
J. Varela, A. S. Brun, A. Strugarek +3
The aim of this study is to analyze the Earth habitability with respect to the direct exposition of the Earth atmosphere to the solar wind along the Suns evolution on the main sequ…
Global-MHD Simulations using MagPIE : Impact of Flux Transfer Events on the Ionosphere
Arghyadeep Paul, Antoine Strugarek, Bhargav Vaidya
This study presents a recently developed two-way coupled magnetosphere-ionosphere model named MagPIE that enables the investigation of the impact of flux transfer events (FTEs) on…
Stellar spectral-type (mass) dependence of the dearth of close-in planets around fast-rotating stars. Architecture of Kepler confirmed single-exoplanet systems compared to star-planet evolution models
R. A. García, C. Gourvès, A. R. G. Santos +8
In 2013 a dearth of close-in planets around fast-rotating host stars was found using statistical tests on Kepler data. The addition of more Kepler and Transiting Exoplanet Survey S…
Self-consistent simulation of photoelectrons in exoplanet winds: Faster ionisation and weaker mass loss rates
Alexande Gillet, Antonio Garcia Munoz, Antoine Strugarek
Planetary mass loss is governed by several physical mechanisms, including photoionisation that may impact the evolution of the atmosphere. Stellar radiation energy deposited as hea…
Investigating the visible phase-curve variability of 55 Cnc e
E. A. Meier Valdés, B. M. Morris, B. -O. Demory +87
55 Cnc e is an ultra-short period super-Earth transiting a Sun-like star. Previous observations in the optical range detected a time-variable flux modulation that is phased with th…
MHD study of extreme space weather conditions for exoplanets with Earth-like magnetospheres: On habitability conditions and radio-emission
J. Varela, A. S. Brun, P. Zarka +3
The present study aims at characterizing the habitability conditions of exoplanets with an Earth-like magnetosphere inside the habitable zone of M stars and F stars like tau Boo, c…
Spin evolution of Venus-like planets subjected to gravitational and thermal tides
Alexandre Revol, Émeline Bolmont, Gabriel Tobie +5
The arrival of powerful instruments will provide valuable data for the characterization of rocky exoplanets. It is then crucial to accurately model the dynamical state of exoplanet…
