Abiotic ozone and oxygen in atmospheres similar to prebiotic earth [PDF]

open access: yes, 2014
The search for life on planets outside our solar system will use spectroscopic identification of atmospheric biosignatures. The most robust remotely detectable potential biosignature is considered to be the detection of oxygen (O2) or ozone (O3 ...

The role of planetary interior in the long-term evolution of atmospheric CO2on Earth-like exoplanets [PDF]

open access: yesAstronomy & Astrophysics, 2021
Context.The long-term carbonate silicate cycle plays an important role in the evolution of Earth’s climate and, therefore, may also be an important mechanism in the evolution of the climates of Earth-like exoplanets. However, given the large diversity in the possible interiors for Earth-like exoplanets, the ensuing evolution of the atmospheric ...

Unveiling the atmospheric evolution of exoplanets

open access: yes, 2021
A thorough characterisation of an exoplanetary system includes also studying the evolution of planetary atmospheres. To this end, we developed a custom tool to estimate the atmospheric content of exoplanets at the dispersal of the protoplanetary disk accounting for the present day system observables. In detail, our tool relies on planetary evolutionary

Spectral evolution of gaseous exoplanet atmospheres due to hydrodynamic escape

open access: yes, 2023
The evolution of stars on grand time-scales affect their surroundings in many ways. Due to their intrinsic rotation, causing strong magnetic activity, they vary greatly in radiative activity in X-ray and ultraviolet (XUV) throughout their lifetime. Planets orbiting these stars close-in could, consequently, be affected by these drastic radiative changes.

On the relative importance of AGN winds for the evolution of exoplanet atmospheres

open access: yesMonthly Notices of the Royal Astronomical Society, 2022
ABSTRACT Recent work investigating the impact of winds and outflows from active galactic nuclei (AGNs) on the habitability of exoplanets suggests that such activity could be deleterious for the long-term survival of planetary atmospheres and the habitability of planets subject to such winds.

Zodiacal exoplanets in time – XIII. Planet orbits and atmospheres in the V1298 Tau system, a keystone in studies of early planetary evolution [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT Studies of planetary systems of stars in star-forming regions and young clusters open a window on the formative stages of planetary evolution. We obtained high-cadence high-resolution infrared spectroscopy of the solar-mass Taurus association-member V1298 Tau during a transit of its 10R⊕-size ‘b’ planet. We measured the systemic

Exoplanet Atmospheric Studies At High Spectral Resolution

open access: yes, 2020
The study of exoplanet atmospheres is essential to understand the formation, evolution and composition of exoplanets. When a planet pass between its host star and an observer, a fraction of the star-light is absorbed by its atmosphere, thus revealing its
