Why M-dwarf flares have limited impact on the atmospheric evaporation of sub-Neptunes and Earth-sized planets
Andrea Caldiroli, Francesco Haardt, Elena Gallo +4
M-type stars are prime targets for exoplanet searches within their habitable zones (HZs). These stars also exhibit significant magnetic flaring activity, particularly during their…
Evaporation of Close-in Sub-Neptunes by Cooling White Dwarfs
Elena Gallo, Andrea Caldiroli, Riccardo Spinelli +5
Motivated by the recent surge in interest concerning white dwarf (WD) planets, this work presents the first numerical exploration of WD-driven atmospheric escape, whereby the high-…
Self-Consistent Modeling of Metastable Helium Exoplanet Transits
Federico Biassoni, Andrea Caldiroli, Elena Gallo +3
Absorption of stellar X-ray and Extreme Ultraviolet radiation in the upper atmosphere of close-in exoplanets can give rise to hydrodynamic outflows, which may lead to the gradual s…
Planetary parameters, XUV environments and mass-loss rates for nearby gaseous planets with X-ray detected host-stars
R. Spinelli, E. Gallo, F. Haardt +4
We leverage Gaia DR2 parallactic distances to deliver new or revised estimates of planetary parameters and X-ray irradiation for a distance-limited ( pc) sample of 27…
Irradiation-driven escape of primordial planetary atmospheres II. Evaporation efficiency of sub-Neptunes through hot Jupiters
Andrea Caldiroli, Francesco Haardt, Elena Gallo +3
Making use of the publicly available 1D photoionization hydrodynamics code ATES we set out to investigate the combined effects of planetary gravitational potential energy ($ϕ_p\equ…
Irradiation-driven escape of primordial planetary atmospheres I. The ATES photoionization hydrodynamics code
Andrea Caldiroli, Francesco Haardt, Elena Gallo +3
Intense X-ray and ultraviolet stellar irradiation can heat and inflate the atmospheres of closely orbiting exoplanets, driving mass outflows that may be significant enough to evapo…
