Habitable planets around the star Gliese 581
Radial velocity surveys are now able to detect terrestrial planets at habitable distance from M-type stars. Recently, two planets with minimum masses below 10 Earth masses were reported in a tripleExpand

Orbital forcing of the martian polar layered deposits
Since the first images of polar regions on Mars revealed alternating bright and dark layers, there has been speculation that their formation might be tied to the planet's orbital climate forcing. ButExpand

Is tidal heating sufficient to explain bloated exoplanets? Consistent calculations accounting for finite initial eccentricity
We present the consistent evolution of short-period exoplanets coupling the tidal and gravothermal evolution of the planet. Contrarily to previous similar studies, our calculations are based on theExpand

Formation of Glaciers on Mars by Atmospheric Precipitation at High Obliquity
Surface conditions on Mars are currently cold and dry, with water ice unstable on the surface except near the poles. However, geologically recent glacierlike landforms have been identified in theExpand

Recent ice-rich deposits formed at high latitudes on Mars by sublimation of unstable equatorial ice during low obliquity
Observations from the gamma-ray spectrometer instrument suite on the Mars Odyssey spacecraft have been interpreted as indicating the presence of vast reservoirs of near-surface ice in high latitudesExpand

Recent formation and evolution of northern Martian polar layered deposits as inferred from a Global Climate Model
[1] We present a time-marching model which simulates the exchange of water ice between the Martian northern cap, the tropics, and a high-latitude surface reservoir. Net annual exchange rates of waterExpand

FALLING TRANSITING EXTRASOLAR GIANT PLANETS
We revisit the tidal stability of extrasolar systems harboring a transiting planet and demonstrate that, independently of any tidal model, none, but one (HAT-P-2b) of these planets has a tidalExpand

Amazonian northern mid-latitude glaciation on Mars: A proposed climate scenario
Recent geological observations in the northern mid-latitudes of Mars show evidence for past glacial activity during the late Amazonian, similar to the integrated glacial landsystems in the DryExpand

Tidal dissipation within hot Jupiters : a new appraisal
Context. Eccentricity or obliquity tides have been proposed as the missing energy source that may explain the anomalously large radius of some transiting “hot Jupiters”. To maintain a non-zero andExpand

Rotational Dynamics of Europa
The rotational state of Europa is only rather poorly constrained at present. It is known to rotate about an axis that is nearly perpendicular to the orbit plane, at a rate that is nearly constant andExpand
