The habitable zone for a given star describes the range of circumstellar distances from the star within which a planet could have liquid water on its surface, which depends upon the stellar properties. Here we describe the development of the habitable zone concept, its application to our own solar system, and its subsequent application to exoplanetary systems. We further apply this to planets in extreme eccentric orbits and show how they may still retain life-bearing properties depending upon… Expand
The Impact of Stellar Distances on Habitable Zone Planets
Among the most highly valued of exoplanetary discoveries are those of terrestrial planets found to reside within the habitable zone (HZ) of the host star. In particular, those HZ planets withExpand
Dynamical Effects on the Habitable Zone for Earth-like Exomoons
With the detection of extrasolar moons (exomoons) on the horizon, it is important to consider their potential for habitability. If we consider the circum stellar Habitable Zone (HZ, often describedExpand
In the Presence of a Wrecking Ball: Orbital Stability in the HR 5183 System
Discoveries of exoplanets using the radial velocity method are progressively reaching out to increasingly longer orbital periods as the duration of surveys continues to climb. The improvingExpand
S-Type and P-Type Habitability in Stellar Binary Systems: A Comprehensive Approach III. Results for Mars, Earth, and super-Earth Planets
In Paper I and II, a comprehensive approach was utilized for the calculation of S-type and P-type habitable regions in stellar binary systems for both circular and elliptical orbits of the binaryExpand
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
Enhanced Habitability on High Obliquity Bodies near the Outer Edge of the Habitable Zone of Sun-like Stars
High obliquity planets represent potentially extreme limits of terrestrial climate, as they exhibit large seasonality, a reversed annual-mean pole-to-equator gradient of stellar heating, and novelExpand
The effect of planetary illumination on climate modelling of Earth-like exomoons
From analytical studies of tidal heating, eclipses and planetary illumination, it is clear that the exomoon habitable zone (EHZ) - the set of moon and host planet orbits that permit liquid water onExpand
Obliquity and Eccentricity Constraints For Terrestrial Exoplanets
Exoplanet discoveries over recent years have shown that terrestrial planets are exceptionally common. Many of these planets are in compact systems that result in complex orbital dynamics. A key stepExpand
Surface flux patterns on planets in circumbinary systems and potential for photosynthesis
Abstract Recently, the Kepler Space Telescope has detected several planets in orbit around a close binary star system. These so-called circumbinary planets will experience non-trivial spatial andExpand
The Catalog of Earth-Like Exoplanet Survey TArgets (CELESTA): A Database of Habitable Zones around Nearby Stars
Locating planets in circumstellar Habitable Zones is a priority for many exoplanet surveys. Space-based and ground-based surveys alike require robust toolsets to aid in target selection and missionExpand


Tidal limits to planetary habitability
The habitable zones (HZs) of main-sequence stars have traditionally been defined as the range of orbits that intercept the appropriate amount of stellar flux to permit surface water on a planet.Expand
This Letter outlines a simple approach to evaluate habitability of terrestrial planets by assuming different types of planetary atmospheres and using corresponding model calculations. Our approachExpand
Earth-like worlds on eccentric orbits: excursions beyond the habitable zone
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)Expand
Habitability of exoplanetary systems with planets observed in transit
We have used the measured properties of the stars in the 79 exoplanetary systems with one or more planets that have been observed in transit, to estimate each system's present habitability. SuchExpand
The evolution of habitable zones during stellar lifetimes and its implications on the search for extraterrestrial life
A stellar evolution computer model has been used to determine changes in the luminosity L and effective temperature Te of single stars during their time on the main sequence. The range of stellarExpand
Moons of giant planets may represent an alternative to the classical picture of habitable worlds. They may exist within the circumstellar habitable zone of a parent star, and through tidal energyExpand
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. Expand
Habitable zones around main sequence stars.
The results suggest that mid-to-early K stars should be considered along with G stars as optimal candidates in the search for extraterrestrial life. Expand
Post-Capture Evolution of Potentially Habitable Exomoons
The satellites of extrasolar planets (exomoons) have been recently proposed as astrobiological targets. Since giant planets in the habitable zone are thought to have migrated there, it is possibleExpand
Habitable moons around extrasolar giant planets
It is argued that rocky moons orbiting these companions could be habitable if the planet–moon system orbits the parent star within the so-called 'habitable zone'10, where life-supporting liquid water could be present. Expand
