A whole-planet model of the Earth without life for terrestrial exoplanet studies
Samantha Gilbert-Janizek, Rory K. Barnes, Peter E. Driscoll +5
As the only known habitable (and inhabited) planet in the universe, Earth informs our search for life elsewhere. Future telescopes like the Habitable Worlds Observatory (HWO) will…
Probing the Origin of Water in Planets within Habitable Zones by HWO
Yasuhiro Hasegawa, Courtney Dressing, Ludmila Carone
How do habitable environments arise and evolve within the context of their planetary systems? This is one fundamental question, and it can be addressed partly by identifying how pl…
The effect of a biosphere on the habitable timespan of stagnant-lid planets and implications for the atmospheric spectrum
Dennis Höning, Ludmila Carone, Philipp Baumeister +6
Temperature-dependent biological productivity controls silicate weathering and thereby extends the potential habitable timespan of Earth. Models and theoretical considerations indi…
From CO- to HO-dominated atmospheres and back -- How mixed outgassing changes the volatile distribution in magma oceans around M dwarf stars
Ludmila Carone, Rory Barnes, Lena Noack +7
We investigate the impact of CO on TRAPPIST-1 e, f and g during the magma ocean stage. These potentially habitable rocky planets are currently the most accessible for astronomi…
