Dependence of Biological Activity on the Surface Water Fraction of Planets
One of the unique features associated with the Earth is that the fraction of its surface covered by land is comparable to that spanned by its oceans and other water […]

Idealized Wind-driven Ocean Circulations On Exoplanets
Motivated by the important role of the ocean in the Earth climate system, here we investigate possible scenarios of ocean circulations on exoplanets using a one-layer shallow water ocean model. […]

Direct Imaging in Reflected Light: Characterization of Older, Temperate Exoplanets With 30-m Telescopes
Direct detection, also known as direct imaging, is a method for discovering and characterizing the atmospheres of planets at intermediate and wide separations. It is the only means of obtaining […]

Role of Gaseous Giants in the Dynamical Evolution of Terrestrial Planets and Water Delivery in the Habitable Zone
In the present research, we study the effects of a single giant planet in the dynamical evolution of water-rich embryos and planetesimals, located beyond the snow line of systems around […]

Role of gaseous giants in the dynamical evolution of terrestrial planets and water delivery in the habitable zone
In the present research, we study the effects of a single giant planet in the dynamical evolution of water-rich embryos and planetesimals, located beyond the snow line of systems around […]

Climates of Warm Earth-like Planets: 3-D Model Simulations
We present a large ensemble of simulations of an Earth-like world with an increasing range of insolation & length of day. We show how important cloud parameterization can be for […]

A Neptune-mass Planet Traversing the Habitable Zone Around HD 180617
Despite their activity, low-mass stars are of particular importance for the search of exoplanets by the means of Doppler spectroscopy, as planets with lower masses become detectable. We report on […]

Atmospheric Circulation and Thermal Phase-Curve Offset of Tidally and Non-Tidally Locked Terrestrial Exoplanets
Using an idealised general circulation model, we investigate the atmospheric circulation of Earth-like terrestrial planets in a variety of orbital configurations. We relax the common assumption of the planet being […]

More Clues That Earth-like Exoplanets Are Indeed Earth-like
A new study from the Georgia Institute of Technology provides new clues indicating that an exoplanet 500 light-years away is much like Earth. Kepler-186f is the first identified Earth-sized planet […]
