A general modeling scheme for assessing the suitability for life of extrasolar planets is presented. The scheme focuses on the identification of the “habitable zone” in main sequence star planetary systems accommodating Earth-like components. Our definition of habitability is based on the long-term possibility of photosynthetic biomass production under geodynamic conditions. Therefore all the pertinent astrophysical, climatological, biogeochemical, and geodynamic processes involved in the…

Dynamic Habitability of Extrasolar Planetary Systems

In this paper, we estimate the likelihood to find habitable Earth-like planets on stable orbits for the extrasolar planetary systems ee Eridani, 55 Cancri, 47 Ursae Majoris, and ρ Coronae Borealis

Habitability of the Goldilocks Planet Gliese 581g: Results from Geodynamic Models

Aims: In 2010, detailed observations have been published that seem to indicate another super-Earth planet in the system of Gliese 581 located in the midst of the stellar climatological habitable

Habitability of super-Earth planets around main-sequence stars including red giant branch evolution: models based on the integrated system approach

Abstract In a previous study published in Astrobiology, we focused on the evolution of habitability of a 10 M⊕ super-Earth planet orbiting a star akin to the Sun. This study was based on a concept of

Circumstellar Habitable Zones to Ecodynamic Domains: A Preliminary Review and Suggested Future Directions

The concept of the Circumstellar Habitable Zone has served the scientific community well for some decades. It slips easily off the tongue, and it would be hard to replace. Recently, however, several

Habitability of super-Earth planets around other suns: models including Red Giant Branch evolution.

A thermal evolution model for a 10 Earth-mass planet orbiting a star like the Sun, based on the integrated system approach, that identifies a so-called photosynthesis-sustaining habitable zone (pHZ), as determined by the limits of biological productivity on the planetary surface.

Habitable Zones in Extrasolar Planetary Systems

If we ask the question about the possible existence of the life outside the Earth, we first have to determine the habitable zone (HZ) for our solar system. The HZ of distances between a main sequence

Planetary habitability: is Earth commonplace in the Milky Way?

The habitable zone (HZ) around a given central star is defined as the region within which an Earth-like planet might enjoy the moderate surface temperatures required for advanced life forms and with the help of a segment of the Drake equation, the number of "Gaias" (i.e. extra-solar terrestrial planets with a globally acting biosphere) is estimated.

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.

Life span of the biosphere

There has been life on Earth for at least 3,500 Myr but the assumption that a comparable future lies ahead may not be justified. Main sequence stars appear to increase their burning rate as they age.
