Many of the recently discovered extrasolar giant planets move around their stars on highly eccentric orbits, and some with e [ges ] 0·7. Systems with planets within or near the habitable zone (HZ) will possibly harbour life on terrestrial-type moons if the seasonal temperature extremes resulting from the large orbital eccentricities of the planets are not too severe. Here we use a three-dimensional general-circulation climate model and a one-dimensional energy-balance model to examine the… 

Pervasive orbital eccentricities dictate the habitability of extrasolar earths.

It is shown that an extrasolar earth is likely to experience a broad range of orbital evolution dictated by the location of a gas-giant planet, which necessitates more focused studies on the effect of eccentricity on the potential for life.

Climate variations on Earth-like circumbinary planets

It is found that the periodic forcing of the atmosphere has a noticeable impact on the planet's climate, but for Earth-like greenhouse gas concentrations, the variable forcing does not change the range of insolation values allowing for habitable climates substantially.

Habitability of planets on eccentric orbits: Limits of the mean flux approximation

Unlike the Earth, which has a small orbital eccentricity, some exoplanets discovered in the insolation habitable zone (HZ) have high orbital eccentricities (e.g., up to an eccentricity of ~0.97 for

Habitability and Water Loss Limits on Eccentric Planets Orbiting Main-sequence Stars

A planet’s climate can be strongly affected by its orbital eccentricity and obliquity. Here we use a one-dimensional energy balance model modified to include a simple runaway greenhouse (RGH)

Habitability of Earth-like planets with high obliquity and eccentric orbits: results from a general circulation model

We explore the implications of seasonal variability for the habitability of idealized Earth-like planets as determined by the two parameters polar obliquity and orbital eccentricity. Commonly, the

Tides and the evolution of planetary habitability.

The tidal evolution of hypothetical terrestrial planets around low-mass stars is calculated and it is shown that tides can evolve planets past the inner edge of the habitable zone, sometimes in less than 1 billion years.

The most common habitable planets – atmospheric characterization of the subgroup of fast rotators

The current search for habitable planets has focused on Earth-like conditions of mass, volatile content and orbit. However, rocky planets following eccentric orbits, and drier than the Earth, may be

The role of dynamics on the habitability of an Earth-like planet

Abstract From the numerous detected planets outside the Solar System, no terrestrial planet comparable with our Earth has been discovered so far. The search for an Exo-Earth is certainly a big
