The Goldilocks problem for detecting water in terrestrial planets: Constraining water abundances in the mid-IR with LIFE
Sarah Rugheimer, Eleonora Alei, Björn S. Konrad +7
We investigate how well the Large Interferometer for Exoplanets (LIFE) mission concept can detect habitable conditions on exoplanets through the presence of atmospheric water vapor…
The PLATO Input Catalogue of targets (tPIC) for the first Long Pointing Field
M. Montalto, G. Piotto, P. M. Marrese +30
The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission is designed to detect terrestrial planets in the habitable zones of solar-type stars. Owing to telemetry constr…
Climates of Terrestrial Exoplanets and Biosignatures
Siddharth Bhatnagar, Emeline Bolmont, Nikita J. Boeren +18
Understanding the climates of terrestrial exoplanets and the detectability of biosignatures is an inherently interdisciplinary challenge, requiring the integration of insights from…
Detecting Atmospheric CO2 Trends as Population-Level Signatures for Long-Term Stable Water Oceans and Biotic Activity on Temperate Terrestrial Exoplanets
Janina Hansen, Daniel Angerhausen, Sascha P. Quanz +6
Identifying key observables is essential for enhancing our knowledge of exoplanet habitability and biospheres, as well as improving future mission capabilities. While currently cha…
Photobombing for the Large Interferometer For Exoplanets (LIFE). A new criterion for target confusion and application to a MIR rotating nulling interferometer
Drinor Cacaj, Daniel Angerhausen, Prabal Saxena +4
One of the primary objectives in modern astronomy is to discover and study planets with characteristics similar to Earth. This pursuit involves analyzing the spectra of exoplanets…
Pursuing Truth: Improving Retrievals on Mid-Infrared Exo-Earth Spectra with Physically Motivated Water Abundance Profiles and Cloud Models
Björn S. Konrad, Sascha P. Quanz, Eleonora Alei +1
Atmospheric retrievals are widely used to constrain exoplanet properties from observed spectra. We investigate how the common nonphysical retrieval assumptions of vertically consta…
