One of these targets, the nearby M3V star GJ 581 (HIP 74995), has received considerable attention in recent years following the announcement by Bon ls et al (2005), hereafter Bon ls05, of a 5 37-day hot-Neptune (GJ 581b, or simply planet-b) around this star More recently, the Geneva group (Udry et al 2007), hereafter Udry07, announced 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
