GJ 436b and the stellar wind interaction: simulations constraints using Ly and H transits
C. Villarreal D'Angelo, A. A. Vidotto, A. Esquivel +2
The GJ 436 planetary system is an extraordinary system. The Neptune-size planet that orbits the M3 dwarf revealed in the Ly line an extended neutral hydrogen atmosphere. This ma…
MOVES IV. Modelling the influence of stellar XUV-flux, cosmic rays, and stellar energetic particles on the atmospheric composition of the hot Jupiter HD 189733b
Patrick Barth, Christiane Helling, Eva E. Stüeken +7
Hot Jupiters provide valuable natural laboratories for studying potential contributions of high-energy radiation to prebiotic synthesis in the atmospheres of exoplanets. In this fo…
Lambda And: A post-main sequence wind from a solar-mass star
D. O Fionnagain, A. A. Vidotto, P. Petit +5
We investigate the wind of lambda And, a solar-mass star that has evolved off the main sequence becoming a sub-giant. We present spectropolarimetric observations and use them to re…
Effects of the stellar wind on the Ly-alpha transit of close-in planets
S. Carolan, A. A. Vidotto, C. Villarreal D'Angelo +1
We use 3D hydrodynamics simulations followed by synthetic line profile calculations to examine the effect increasing the strength of the stellar wind has on observed Ly- transit…
Identifying solar-like magnetic cycles with Zeeman-Doppler-Imaging (ZDI)
Lisa T. Lehmann, Gaitee A. J. Hussain, Aline A. Vidotto +2
We are reaching the point where spectropolarimetric surveys have run for long enough to reveal solar-like magnetic activity cycles. In this paper we investigate what would be the b…
Coupling thermal evolution of planets and hydrodynamic atmospheric escape in MESA
Daria Kubyshkina, Aline A. Vidotto, Luca Fossati +1
The long-term evolution of hydrogen-dominated atmospheres of sub-Neptune-like planets is mostly controlled by two factors: a slow dissipation of the gravitational energy acquired a…
