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 zone and could sustain liquid water on their surfaces. During the exten

Searching for Atmospheric Bioindicators in Planets around the Two Nearby Stars, Proxima Centauri and Epsilon Eridani-Test Cases for Retrieval of Atmospheric Gases with Infrared Spectroscopy
Autor: Denis Defrere, Feng Tian, A. García Muñoz, Heike Rauer, A. Léger, M Godolt, John Lee Grenfell
Publikováno v: Astrobiology. 19(6)
We tested the ability of thermal infrared spectroscopy to retrieve assumed atmospheric compositions for different types of planets orbiting Proxima Centauri and Epsilon Eridani. Six cases are considered, covering a range of atmospheric compositions a

New Insights into Cosmic Ray induced Biosignature Chemistry in Earth-like Atmospheres
Autor: Franz Schreier, Markus Scheucher, John Lee Grenfell, M. Godolt, Heike Rauer, Fabian Wunderlich
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 exoplanet community. We investigate potential biosignatures of planets hav

The habitability of a stagnant-lid Earth
Autor: Nicola Tosi, Athanasia Nikolaou, John Lee Grenfell, B. Stracke, Tilman Spohn, Doris Breuer, M. Godolt, Thomas Ruedas, Dennis Höning, Ana-Catalina Plesa
Plate tectonics is a fundamental component for the habitability of the Earth. Yet whether it is a recurrent feature of terrestrial bodies orbiting other stars or unique to the Earth is unknown. The stagnant lid may rather be the most common tectonic

Fahndung nach der zweiten Erde

Publikováno v: Physik in unserer Zeit. 44:64-71
Erdahnliche Planeten oder Supererden, bei denen man Transit- und Bedeckungsereignisse beobachten kann, sind fur spektroskopische Untersuchungen der Atmosphare geeignete Objekte. Es ist aber keineswegs eindeutig zu sagem, welche Bestandteile der Atmos

Assessing the habitability of planets with Earth-like atmospheres with 1D and 3D climate modeling
Autor: John Lee Grenfell, Markus Kunze, M. Godolt, D. Kitzmann, Ulrike Langematz, Heike Rauer, B. Stracke, A. B. C. Patzer
The habitable zone (HZ) describes the range of orbital distances around a star where the existence of liquid water on the surface of an Earth-like planet is in principle possible. While 3D climate studies can calculate the water vapor, ice albedo, an

Monthly notices of the Royal Astronomical Society, 452(4), pp. 3752-3758. Oxford University Press 10.1093/mnras/stv1487
Ocean planets are volatile rich planets, not present in our Solar System, which are thought to be dominated by deep, global oceans. This results in the formation of high-pressure water ice, separating the planetary crust from the liquid ocean and, th

Ozone is an important radiative trace gas in the Earth's atmosphere. The presence of ozone can significantly influence the thermal structure of an atmosphere, and by this e.g. cloud formation. Photochemical studies suggest that ozone can form in carb

The potential habitability of a terrestrial planet is usually defined by the possible existence of liquid water on its surface. The potential presence of liquid water depends on many factors such as, most importantly, surface temperatures. The proper
