sunset : A database of synthetic atmospheric-escape transmission spectra for nearly every transiting planet [PDF]
Astronomy & AstrophysicsStudying atmospheric escape from exoplanets can provide important clues about the formation and evolution of exoplanets. Observational evidence of atmospheric escape has been obtained through transit spectroscopy in strong spectral lines of various ...

The Implications of Thermal Hydrodynamic Atmospheric Escape on the TRAPPIST-1 Planets [PDF]
The Planetary Science JournalJWST observations of the seven-planet TRAPPIST-1 system will provide an excellent opportunity to test outcomes of stellar-driven evolution of terrestrial planetary atmospheres, including atmospheric escape, ocean loss, and abiotic oxygen production ...

THERMALLY DRIVEN ATMOSPHERIC ESCAPE [PDF]
The Astrophysical Journal, 2010 Accurately determining escape rates from a planet's atmosphere is critical for determining its evolution. Escape can be driven by upward thermal conduction of energy deposited well below the exobase, as well as by non-thermal processes produced by energy deposited in the exobase region. Recent applications of a model for escape driven by upward thermal

The effect of a small amount of hydrogen in the atmosphere of ultrahot magma-ocean planets: atmospheric composition and escape [PDF]
Astronomy & Astrophysics, 2023 Here we investigate how small amounts of hydrogen (much smaller than the mass of the exoplanet) above a magma ocean on a rocky exoplanet may modify the atmospheric chemistry and atmospheric escape.We use a chemical model of a magma ocean coupled to a gas

The Escape of Planetary Atmospheres [PDF]
Symposium - International Astronomical Union, 1974 The problem of escape of atmospheres from the Moon and planets has roots deep in ancient history. Many of the great philosophers of the past regarded the Earth's atmosphere as a medium extending to infinity, with a stationary Earth imbedded at the center.

Stellar flares versus luminosity: XUV-induced atmospheric escape and planetary habitability [PDF]
Monthly Notices of the Royal Astronomical Society Letters, 2020 Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (1030–1038 erg), a fraction of which lies in X-rays and extreme ultraviolet (XUV).

Earth and Planetary Physics, 2022 Tailward ion outflows in the Martian-induced magnetotail are known to be one of the major channels for Martian atmospheric escape. On the basis of nearly 6.5 years of observations from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we ...

The dichotomy of atmospheric escape in AU Mic b [PDF]
, 2020 Here, we study the dichotomy of the escaping atmosphere of the newly discovered close-in exoplanet AU Mic b. On one hand, the high EUV stellar flux is expected to cause a strong atmospheric escape in AU Mic b.

The high-energy environment and atmospheric escape of the mini-Neptune K2-18 b [PDF]
Astronomy & Astrophysics, 2020 K2-18 b is a transiting mini-Neptune that orbits a nearby (38 pc), cool M3 dwarf and is located inside its region of temperate irradiation. We report on the search for hydrogen escape from the atmosphere K2-18 b using Lyman-α transit spectroscopy with ...

Influence of the Sun-like magnetic cycle on exoplanetary atmospheric escape [PDF]
, 2020 Stellar high-energy radiation (X-ray and extreme ultraviolet, XUV) drives atmospheric escape in close-in exoplanets. Given that stellar irradiation depends on the stellar magnetism and that stars have magnetic cycles, we investigate how cycles affect the
