The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth
- G. Arney, S. Domagal-Goldman, +6 authors M. Trainer
- Geology, Environmental Science
- Astrobiology
- 14 October 2016
Abstract Recognizing whether a planet can support life is a primary goal of future exoplanet spectral characterization missions, but past research on habitability assessment has largely ignored the… Expand
The inner edge of the habitable zone for synchronously rotating planets around low-mass stars using general circulation models
- R. Kopparapu, E. Wolf, +5 authors S. Mahadevan
- Physics
- 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… Expand
Fractal Organic Hazes Provided an Ultraviolet Shield for Early Earth
The Past Looks Hazy During the first couple of billion years of Earth's history, the Sun is thought to have been 30% less luminous than today, yet the surface of the planet was warm enough to prevent… Expand
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… Expand
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… Expand
Habitable Moist Atmospheres On Terrestrial Planets Near the Inner Edge Of the Habitable Zone Around M-dwarfs
- R. Kopparapu, E. Wolf, +4 authors K. Heng
- Physics
- 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… Expand
Pale Orange Dots: The Impact of Organic Haze on the Habitability and Detectability of Earthlike Exoplanets
- G. Arney, V. Meadows, +5 authors E. Schwieterman
- Environmental Science, 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… Expand
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.… Expand
Hospitable archean climates simulated by a general circulation model.
Evidence from ancient sediments indicates that liquid water and primitive life were present during the Archean despite the faint young Sun. To date, studies of Archean climate typically utilize… Expand
Demarcating circulation regimes of synchronously rotating terrestrial planets within the habitable zone
- J. Haqq-Misra, E. Wolf, Manoj Joshi, X. Zhang, R. Kopparapu
- Physics
- 1 October 2017
We investigate the atmospheric dynamics of terrestrial planets in synchronous rotation within the habitable zone of low-mass stars using the Community Atmosphere Model (CAM). The surface temperature… Expand
