and Fabrycky (2010) published a detailed study of the e ects of aliasing on the GJ 581 data set of Mayor09 They concluded that the 67-day period of GJ 581c remains ambiguous, and favored a period of 1 0125 days that produced aliases at both 67 days and 83 days The Gliese 581 system exerts an outsize fascination when compared to many of the
Introduction: Gliese 581 is a M3V red dwarf star approx 2 light years away 2 Radial velocity (RV) measurements suggest that it has a planetary system of four planets (b-e) [1- 3], with the possibility of two additional, unconfirmed planets g and f [4-10] Gliese 581 e is a low mass planet with a minimum mass of 1 9
cused on the Gl 581 planetary system (also designated GJ 581 in the literature) It was already known to harbor three planets, including two super-Earth planets that straddle its habitable zone: Gl 581 b with a period of 5 37d (Bonfils et al 2005b), Gl 581 c (period 12 9d) and d (period 82d) (Udry et al 2007) Armed with additional HARPS
longer for inner planets e and b Discussion: While the transfer of ejecta between planets is possible in the Gliese 581 system, the poten-tially habitable planets are more biologically isolated Any astrobiological material existing on Gliese 581 d, or one of its hypothetical exomoons, has a small
bar spanning the given distances Note that Gliese c, g and d are located in the HZ of Gliese 581 Because Gliese 581 g is located near the center of this zone and is very likely to be warm enough for there to be liquid water, which is an essential ingredient for life Gliese 581c may be too hot and Gliese 581 d may be too cold
Googling this and checking Wikipedia on Feb 23, 2011: Gliese 581 has a mass of 0 31 that of the Sun and a luminosity of 1 3 that of the Sun Six planets are believed to be orbiting it Gliese 581c has a mass of about 5 times that of Earth, making it very Earth-like

Gliese 581c Source: ESO M dwarf stars M dwarfs are ideal stars to observe in order to find small planets • Low mass - M dwarfs are low mass stars thus it is easier to detect lower mass planets around them • Low luminosity - habital zones for M dwarfs are closer (∼ 0 1 A U ) Gliese 581 Gliese 581 is a M dwarf star
