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…
The Effects of Magnetic Fields on Observational Signatures of Atmospheric Escape in Exoplanets: Double Tail Structures
S. Carolan, A. A. Vidotto, G. Hazra +2
Using 3D radiative MHD simulations and Lyman- transit calculations, we investigate the effect of magnetic fields on the observational signatures of atmospheric escape in exoplan…
The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf
O. Barragán, D. J. Armstrong, D. Gandolfi +103
We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…
