Astronomy c ESO 2007 Astrophysics
The M-type star Gl 581 hosts at least 3 planets which were detected using radial velocity measurements by Bon ls et al (2005)(planet b ) and Udryet al (2007)(planets c and d ) The properties of this star and its planets are given in Table 1 Before this discovery only two exoplanets were known to have |

Considerations for the habitable zone of super-Earth planets
Aims We assess the possibility that planets Gliese 581 c and d are within the habitable zone Methods In analogy with our solar system we use an empirical definiti on of the habitable zone We include assumptions such as planetary climates and atmospheric circulation on gravitationally locked synchronous rotation |

The habitability of super-Earths in Gliese 581
The main question is whether any of the two super-Earths around Gl 581 can harbour life i e that any of the planets lies within the habitable zone (HZ) As a first approximation Udry et al (2007) computed an equilibrium surface temperature for Gl 581c of 20 C for an albedo of 0 5 |

Quel est l'ordre de grandeur du rayon de Gliese 581 c ?
Caractéristiques orbitales.
Gliese 581 c possède une période orbitale (« année ») de 13 jours terrestres et son rayon orbital ne représente que 7 % de celui de la Terre, c'est-à-dire qu'il mesure seulement 11 millions de kilomètres, alors que la Terre est à 150 millions de kilomètres du Soleil.- Une exoplanète, ou planète extrasolaire, est une planète située en dehors de notre système solaire et orbitant autour d'une étoile ou d'une naine brune.
Tout objet de masse planétaire tournant autour d'une étoile est une exoplanète.
