Impact of Cosmic Rays on Atmospheric Ion Chemistry and Spectral Transmission Features of TRAPPIST-1e
Konstantin Herbst, Andreas Bartenschlager, John Lee Grenfell +10
Ongoing observing projects like the James Webb Space Telescope (JWST) and future missions offer the chance to characterize Earth-like exoplanetary atmospheres. Thereby, M-dwarfs ar…
Assessment of a Physics-based Retrieval of Exoplanet Atmospheric Temperatures from Infrared Emission Spectra
Franz Schreier, J. Lee Grenfell, Fabian Wunderlich +1
Atmospheric temperatures are to be estimated from thermal emission spectra of Earth-like exoplanets orbiting M-stars as observed by current and future planned missions. To this end…
Large Interferometer For Exoplanets (LIFE): V. Diagnostic potential of a mid-infrared space-interferometer for studying Earth analogs
Eleonora Alei, Björn S. Konrad, Daniel Angerhausen +6
An important future goal in exoplanetology is to detect and characterize potentially habitable planets. Using nulling interferometry, LIFE will allow us to constrain the radius and…
Atmospheric processes affecting methane on Mars
John Lee Grenfell, Fabian Wunderlich, Miriam Sinnhuber +6
It is currently uncertain as to whether methane exists on Mars. Data from the Curiosity Rover suggests a background methane concentration of a few tenths parts per billion whereas…
Large Interferometer For Exoplanets (LIFE): III. Spectral resolution, wavelength range and sensitivity requirements based on atmospheric retrieval analyses of an exo-Earth
B. S. Konrad, E. Alei, D. Angerhausen +9
Temperate terrestrial exoplanets are likely common objects, but their discovery and characterization is very challenging. Concepts for optimized space missions to overcome these ch…
Influence of Biomass Emissions upon Habitability, Biosignatures and Detectability in Earth-like Atmospheres
Stefanie Gebauer, Iva Vilović, John Lee Grenfell +3
We investigate atmospheric responses of modeled hypothetical Earth-like planets in the habitable zone of the M-dwarf AD Leonis to reduced oxygen (O2), removed biomass (dead Earth),…
Large Interferometer For Exoplanets (LIFE): I. Improved exoplanet detection yield estimates for a large mid-infrared space-interferometer mission
S. P. Quanz, M. Ottiger, E. Fontanet +68
One of the long-term goals of exoplanet science is the atmospheric characterization of dozens of small exoplanets in order to understand their diversity and search for habitable wo…
Characterizing Atmospheres of Transiting Earth-like Exoplanets Orbiting M Dwarfs with James Webb Space Telescope
Megan T. Gialluca, Tyler D. Robinson, Sarah Rugheimer +1
A number of transiting, potentially habitable Earth-sized exoplanets have recently been detected around several nearby M dwarf stars. These worlds represent important targets for a…
Detectability of biosignatures on LHS 1140 b
Fabian Wunderlich, Markus Scheucher, John Lee Grenfell +4
Terrestrial extrasolar planets around low-mass stars are prime targets when searching for atmospheric biosignatures with current and near-future telescopes. The habitable-zone Supe…
Distinguishing between wet and dry atmospheres of TRAPPIST-1 e and f
Fabian Wunderlich, Markus Scheucher, Mareike Godolt +7
The nearby TRAPPIST-1 planetary system is an exciting target for characterizing the atmospheres of terrestrial planets. The planets e, f and g lie in the circumstellar habitable zo…
Consistently Simulating a Wide Range of Atmospheric Scenarios for K2-18b with a Flexible Radiative Transfer Module
M. Scheucher, F. Wunderlich, J. L. Grenfell +6
The atmospheres of small, potentially rocky exoplanets are expected to cover a diverse range in composition and mass. Studying such objects therefore requires flexible and wide-ran…
SVEEEETIES: Singular vector expansion to estimate Earth-like exoplanet temperatures from infrared emission spectra
Franz Schreier, Steffen Städt, Fabian Wunderlich +2
Context. Detailed characterizations of exoplanets are moving to the forefront of planetary science. Temperature is a key marker for understanding atmospheric physics and chemistry.…
Detectability of atmospheric features of Earth-like planets in the habitable zone around M dwarfs
F. Wunderlich, M. Godolt, J. L. Grenfell +6
We investigate the detectability of atmospheric spectral features of Earth-like planets in the habitable zone (HZ) around M dwarfs with the future James Webb Space Telescope (JWST)…
New Insights into Cosmic Ray induced Biosignature Chemistry in Earth-like Atmospheres
Markus Scheucher, J. L. Grenfell, F. Wunderlich +3
With the recent discoveries of terrestrial planets around active M-dwarfs, destruction processes masking the possible presence of life are receiving increased attention in the exop…
