Interpreting exoplanet biosignatures with a coupled atmosphere-interior-geochemical evolution model

2021
<p>The atmospheric evolution of rocky planets is shaped by a range of astrophysical, geophysical, and geochemical processes. Interpreting observations of potentially habitable exoplanets will require an improved understanding of how these competing influences interact on long timescales.

Interior structure, mantle-atmosphere co-evolution, and habitability of low-mass exoplanets

2023
Um grundlegende Fragen der Planetenforschung zu beantworten, ist ein fundiertes Verständnis der Zusammensetzung und der Prozesse im Inneren von Exoplaneten eine essenzielle Voraussetzung. Solche Fragen beinhalten beispielsweise, welche Arten von Planeten es geben könnte, welche Mechanismen die Planetenentstehung und -entwicklung steuern, wie ...

Haze Evolution in Temperate Exoplanet Atmospheres: the Laboratory Perspective

2022
With thousands of confirmed detections of exoplanets, recent efforts are focusing on characterizing their atmospheres through transmission spectroscopy. However, opacity sources such as condensation clouds and photochemical hazes have been found to be common in exoplanet atmospheres, muting spectroscopic features of atmospheric species.

Coupling the Atmospheric and Dynamical Evolution of Close-in Exoplanets

The vast majority of the detected exoplanets orbit in less than a month around their star, in extreme conditions unmet in the Solar System. The demographics of these close-in planets exhibit a striking feature: the lack of Neptune-size worlds on very short orbits, also dubbed the "Neptunian desert", which challenges our understanding of planetary ...

The Orbital Imperative: Charting Cosmic Evolution from Gamma-Ray Bursts to Exoplanet Atmospheres

This paper explores the intricate connection between early universe energetic phenomena, specifically Gamma-Ray Bursts (GRBs), and the later-stage evolution of planetary systems, as evidenced by exoplanet atmospheres. We propose an "orbital imperative" framework, suggesting that gravitational dynamics and the resulting distribution of matter play a ...
