The evolution of habitable climates under the brightening Sun
On water‐dominated planets, warming from increased solar insolation is strongly amplified by the water vapor greenhouse feedback. As the Sun brightens due to stellar evolution, Earth will become…
Assessing the Habitability of the TRAPPIST-1 System Using a 3D Climate Model
- E. Wolf
- Geology, Physics
- 16 March 2017
The TRAPPIST-1 system provides an extraordinary opportunity to study multiple terrestrial extrasolar planets and their atmospheres. Here we use the National Center for Atmospheric Research Community…

The inner edge of the habitable zone for synchronously rotating planets around low-mass stars using general circulation models
- R. Kopparapu, E. Wolf, S. Mahadevan
- Physics, Geology
- 16 February 2016
Terrestrial planets at the inner edge of the habitable zone of late-K and M-dwarf stars are expected to be in synchronous rotation, as a consequence of strong tidal interactions with their host…
Pale Orange Dots: The Impact of Organic Haze on the Habitability and Detectability of Earthlike Exoplanets
- G. Arney, V. Meadows, E. Schwieterman
- Geology, Physics
- 1 October 2016
Hazes are common in known planet atmospheres, and geochemical evidence suggests early Earth occasionally supported an organic haze with significant environmental and spectral consequences. The UV…
Habitable Moist Atmospheres On Terrestrial Planets Near the Inner Edge Of the Habitable Zone Around M-dwarfs
- R. Kopparapu, E. Wolf, K. Heng
- Physics, Geology
- 29 May 2017
Terrestrial planets in the habitable zones (HZs) of low-mass stars and cool dwarfs have received significant scrutiny recently because their shorter orbital periods increase their chances of…
Delayed onset of runaway and moist greenhouse climates for Earth
As the Sun slowly grows brighter over its main sequence lifetime, habitability on Earth's surface will eventually become threatened probably leading to moist and then runaway greenhouse climates.…
