p-winds: an open-source Python code to model planetary outflows and upper atmospheres
Leonardo A. Dos Santos, Aline A. Vidotto, Shreyas Vissapragada +6
Atmospheric escape is considered to be one of the main channels for evolution in sub-Jovian planets, particularly in their early lives. While there are several hypotheses proposed…
Atmospheric mass loss and stellar wind effects in young and old systems II: Is TOI-942 the past of TOI-421 system?
Daria Kubyshkina, Aline A. Vidotto, Carolina Villarreal D'Angelo +3
The two planetary systems TOI-942 and TOI-421 share many similar characteristics, apart from their ages (50~Myr and 9~Gyr). Each of the stars hosts two sub-Neptune-like planets at…
Atmospheric mass loss and stellar wind effects in young and old systems I: comparative 3D study of TOI-942 and TOI-421 systems
Daria Kubyshkina, Aline A. Vidotto, Carolina Villarreal D'Angelo +3
At young ages, when radiation from the host star is high, and the planet is hot and inflated after formation, planetary atmospheric mass loss can be extremely strong compared to ol…
The impact of coronal mass ejections and flares on the atmosphere of the hot Jupiter HD189733b
Gopal Hazra, Aline A. Vidotto, Stephen Carolan +2
High-energy stellar irradiation can photoevaporate planetary atmospheres, which can be observed in spectroscopic transits of hydrogen lines. For the exoplanet HD189733b, multiple o…
Coronal mass ejections and type II radio emission variability during a magnetic cycle on the solar-type star Eridani
Dúalta Ó Fionnagáin, Robert D. Kavanagh, Aline A. Vidotto +5
We simulate possible stellar coronal mass ejection (CME) scenarios over the magnetic cycle of Eridani (18 Eridani; HD 22049). We use three separate epochs from 2008, 2011, and…
Galactic cosmic ray propagation through M dwarf planetary systems
A. L. Mesquita, D. Rodgers-Lee, A. A. Vidotto +2
Quantifying the flux of cosmic rays reaching exoplanets around M dwarfs is essential to understand their possible effects on exoplanet habitability. Here, we investigate the propag…
