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 ...

Surveying the stellar drivers of exoplanet evolution for the first time with the ESCAPE small explorer mission

Astronomical Applications
The long-term stability of exoplanetary atmospheres depends critically on the extremeultraviolet (EUV) photon and high-energy particle fluxes from the host star.

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.

Transiting Exoplanet Atmospheres in the Era of JWST

Reviews in Mineralogy & Geochemistry
The field of exoplanet atmospheric characterization has recently made considerable advances with the advent of high-resolution spectroscopy from large ground-based telescopes and the commissioning of the James Webb Space Telescope (JWST). We have entered

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system

Nature
Young exoplanets provide an important link between understanding planet formation and atmospheric evolution1. Direct imaging spectroscopy allows us to infer the properties of young, wide-orbit, giant planets with high signal-to-noise ratio.

Helium Atmospheres May Hide in Current Exoplanet Analysis Frameworks

Astrophysical Journal Letters
The increasing number of detailed exoplanet observations offers an opportunity to refine our analyses and interpretations. Here, we show that atmospheres that appear volatile-rich and/or cloudy may instead be helium-rich.

Exoplanet explorer: a single spacecraft nulling interferometer

International Conference on Space Optics
One of the most ambitious goals of modern astronomy is to uncover signs of extraterrestrial biological activity, primarily achieved through spectroscopic analysis of light emitted by exoplanets to identify specific atmospheric molecules.

The Age and High-energy Environment of the Very Young Transiting Exoplanet TOI 1227b

The mid-M star TOI 1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascertaining its age and the influence of its high-energy radiation on the ...
