Planetary atmospheric escape and disk formation around WDJ0914+1914

C. Villarreal D'Angelo, M. P. Ronco, M. R. Schreiber +3

The spectrum of the white dwarf WD J091405.30+191412.25 displays the absorption and double-peaked emission lines of the volatiles hydrogen, oxygen, and sulfur. This unique characte…

The effects of stellar activity cycles on planetary atmospheric escape and the HeI 1083nm transit signature

Andrew P. Allan, Aline A. Vidotto, Jorge Sanz-Forcada +1

The HeI 1083nm transit signature is commonly used in tracing escaping planetary atmospheres. However, it can be affected by stellar activity, complicating detections and interpreta…

Magnetic interaction of stellar coronal mass ejections with close-in exoplanets: implication on planetary mass loss and Ly- transits

Gopal Hazra, Aline A. Vidotto, Stephen Carolan +2

Coronal Mass Ejections (CMEs) erupting from the host star are expected to have effects on the atmospheric erosion processes of the orbiting planets. For planets with a magnetospher…

Evolution of helium triplet transits of close-in gas giants orbiting K-dwarfs

Andrew P. Allan, Aline A. Vidotto, Carolina Villarreal D'Angelo +2

Atmospheric escape in exoplanets has traditionally been observed using hydrogen Lyman- and H- transmission spectroscopy, but more recent detections have utilised the metastab…

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…
