Abstract:
The GJ 581 planetary system is already known to harbour three planets,
including two super-Earth planets that straddle its habitable zone. We
report the detection of an additional planet - GJ 581e - with a
minimum mass of 1.9M{earth}. With a period of 3.15 days, it is the
innermost planet of the system and has a ∼5% transit probability. We
also correct our previous confusion about the orbital period of GJ
581d (the outermost planet) with a one-year alias, benefitting from an
extended time span and many more measurements. The revised period is
66.8 days, and positions the semi-major axis inside the habitable zone
of the low mass star. The dynamical stability of the 4-planet system
imposes an upper bound on the orbital plane inclination. The planets
cannot be more massive than approximately 1.6 times their minimum
mass.
Description:
The paper reports the discovery of a 1.9M{earth} planet orbiting
the nearby M dwarf GJ 581 (already known to host 3 planets). Here we
list the radial-velocity data measured with HARPS (a high-resolution
spectrograph providing high precision radial velocities) and the
spectroscopic indices measured on the same spectra.
