Spectropolarimetric Characterisation Of Exoplanet Host Stars In Preparation Of The Ariel Mission II. The magnetised wind environment of TOI-1860, DS Tuc A, and HD 63433

We update the status of the spectropolarimetric campaign dedicated to characterise the magnetic field properties of a sample of known exoplanet-hosting stars included in the current target list of the […]

The Impact Of Stellar Winds And Tidal Locking Effects On The Habitability Of Earth-like Exoplanets Around M Dwarf Stars

We present an assessment of the effects of stellar wind magnetic and mechanical components on the habitability of Earth-like exoplanets orbiting the inner and outer radii of the habitable zone […]

Ohmic Heating In The Upper Atmosphere of Hot Exoplanets The Influence of a Time-varying Magnetic Field

Exoplanets on close-in orbit are subject to intense X-ray and ultraviolet (XUV) irradiation from their star. Their atmosphere therefore heats up, sometimes to the point where it thermally escapes from […]

MHD Simulations of the Space Weather in Proxima b: Habitability Conditions and Radio Emission

The habitability of exoplanets hosted by M-dwarf stars dramatically depends on their space weather. We present 3D magneto-hydrodynamic simulations to characterise the magneto-plasma environment and thus the habitability of the […]
