Dynamic Meteorology at the Photosphere of HD 209458b

We calculate the meteorology of the close-in transiting extrasolar planet HD 209458b using a global, three-dimensional atmospheric circulation model. Dynamics are driven by perpetual irradiation of one hemisphere of this tidally locked planet. The simulation predicts global temperature contrasts of ~500 K at the photosphere and the development of a steady superrotating jet. The jet extends from the equator to midlatitudes and from the top model layer at 1 mbar down to 10 bar at the base of the… Expand

Persistent circumpolar vortices on the extrasolar giant planet HD 37605 b
Aims. We examine the atmospheric dynamics on the extrasolar gas giant HD 37605 b (P = 54.2 d). As this planet's orbit is highly eccentric (e = 0.737), the intensity of stellar heating varies by aExpand
Observational Consequences of Hydrodynamic Flows on Hot Jupiters
We use a grid-based shallow water model to simulate the atmospheric dynamics of the transiting hot Jupiter HD 209458b. Under the usual assumption that the planet is in synchronous rotation with zeroExpand

Detailed models are compared to recent infrared observations of the nearby extrasolar planet HD 189733b. It is demonstrated that atmospheric water is present and that the planet's day side has aExpand
Radiative Hydrodynamic Simulations of HD209458b: Temporal Variability

The changing phases of extrasolar planet CoRoT-1b
Optical photometric data obtained over 36 planetary orbits of the transiting hot Jupiter CoRoT-1b are consistent with the nightside hemisphere of the planet being entirely black, with the dayside flux dominating the optical phase curve. Expand

A map of the day–night contrast of the extrasolar planet HD 189733b
Observations of HD 189733, the closest of these eclipsing planetary systems, over half an orbital period are reported, from which a ‘map’ of the distribution of temperatures is constructed, indicating that energy from the irradiated dayside is efficiently redistributed throughout the atmosphere.
