A photochemical model for the carbon-rich planet WASP-12b
Ravi kumar Kopparapu, James F. Kasting, Kevin J. Zahnle
The hot Jupiter WASP-12b is a heavily irradiated exoplanet in a short period orbit around a G0-star with twice the metallicity of the Sun. A recent thermochemical equilibrium analy…
Faint young Sun paradox remains
Colin Goldblatt, Kevin J. Zahnle
The Sun was fainter when the Earth was young, but the climate was generally at least as warm as today; this is known as the `faint young Sun paradox'. Rosing et al. [1] claim that…
The Role of Ejecta in the Small Crater Populations on the Mid-Sized Saturnian Satellites
Edward B. Bierhaus, Luke Dones, José Luis Alvarellos +1
We find evidence that crater ejecta play an important role in the small crater populations on the Saturnian satellites, and more broadly, on cratered surfaces throughout the Solar…
The Atmospheric Chemistry of GJ 1214b: Photochemistry and Clouds
Eliza Miller-Ricci Kempton, Kevin Zahnle, Jonathan J. Fortney
Recent observations of the transiting super-Earth GJ 1214b reveal that its atmosphere may be hydrogen-rich or water-rich in nature, with clouds or hazes potentially affecting its t…
Clouds and the Faint Young Sun Paradox
Colin Goldblatt, Kevin J. Zahnle
We investigate the role which clouds could play in resolving the Faint Young Sun Paradox (FYSP). Lower solar luminosity in the past means that less energy was absorbed on Earth (a…
