Connection between planetary He I 10830 Ã absorption and extreme-ultraviolet emission of planet-host stars
J. Sanz-Forcada, M. López-Puertas, M. Lampón +13
Context. The detection of the He I 10830 A triplet in exoplanet atmospheres has opened a new window for probing planetary properties, including atmospheric escape. Unlike Lyman alp…

The MOPYS project: A survey of 70 planets in search of extended He I and H atmospheres. No evidence of enhanced evaporation in young planets
J. Orell-Miquel, F. Murgas, E. Pallé +30
During the first Gyr of their life, exoplanet atmospheres suffer from different atmospheric escape phenomena that can strongly affect the shape and morphology of the exoplanet itse…

Probing atmospheric escape through metastable He I triplet lines in 15 exoplanets observed with SPIRou
A. Masson, S. Vinatier, B. Bézard +23
For several years, the metastable helium triplet line has been successfully used as a tracer to probe atmospheric escape in transiting exoplanets. This absorption in the near-infra…
