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… Expand
Pervasive orbital eccentricities dictate the habitability of extrasolar earths.
TLDR
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. Expand

TLDR
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. Expand
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 forExpand
Tides and the evolution of planetary habitability.
TLDR
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. Expand
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 1-dimensional energy balance model modified to include a simple runaway greenhouse (RGH)Expand
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 beExpand
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 bigExpand
Climate of Earth-like planets with high obliquity and eccentric orbits: Implications for habitability conditions
Abstract We explore the effects of seasonal variability for the climate of Earth-like planets as determined by the two parameters polar obliquity and orbital eccentricity using a general circulationExpand
Effects of variable eccentricity on the climate of an Earth-like world
The Kepler era of exoplanetary discovery has presented the Astronomical community with a cornucopia of planetary systems very different from the one which we inhabit. It has long been known thatExpand
Dynamic habitability for Earth-like planets in 86 extrasolar planetary systems
Abstract In this paper we estimate the likelihood to find habitable Earth-like planets on stable orbits for 86 selected extrasolar planetary systems, where luminosity, effective temperature andExpand
