Journal ArticleDOI
Habitable Zones Around Main-Sequence Stars: New Estimates
Ravi Kumar Kopparapu,Ramses M. Ramirez,James F. Kasting,Vincent Eymet,Tyler D. Robinson,Tyler D. Robinson,Suvrath Mahadevan,Ryan Terrien,Shawn Domagal-Goldman,Shawn Domagal-Goldman,Victoria S. Meadows,Victoria S. Meadows,Rohit Deshpande +12 more
TL;DR: In this article, an updated 1D radiative-convective, cloud-free climate model is used to obtain new estimates for HZ widths around F, G, K, and M stars.
Journal ArticleDOI
Habitable zones around main-sequence stars: Dependence on planetary mass
Ravi Kumar Kopparapu,Ramses M. Ramirez,James SchottelKotte,James F. Kasting,Shawn Domagal-Goldman,Shawn Domagal-Goldman,Vincent Eymet +6 more
TL;DR: In this article, the authors present estimates of habitable zones (HZs) around stars with stellar effective temperatures in the range 2600 K-7200 K, for planetary masses between 0.1M and 5M.
Journal ArticleDOI
A revised, hazy methane greenhouse for the Archean Earth.
TL;DR: In this article, an error in the CH4 absorption coefficients, combined with the predicted early onset of climatically cooling organic haze, suggest that the amount of greenhouse warming by CH4 was more limited and that pCO2 must therefore have been ≥003 bar.
Journal ArticleDOI
Exoplanet Biosignatures: Understanding Oxygen as a Biosignature in the Context of Its Environment.

TL;DR: The coevolution of life with the early Earth's environment is examined to identify how the interplay of sources and sinks may have suppressed O2 release into the atmosphere for several billion years, producing a false negative for biologically generated O2.
Journal ArticleDOI
A bistable organic-rich atmosphere on the Neoarchaean Earth
Aubrey L. Zerkle,Mark Claire,Mark Claire,Shawn Domagal-Goldman,Shawn Domagal-Goldman,James Farquhar,Simon W. Poulton +6 more
TL;DR: In this article, the Ghaap Group sediments from the 2.65-2.5 billion-year-old Earth were used to reconstruct ocean and atmospheric chemistry during this time.
