Abstract:
This Letter reports on the detection of two super-Earth planets in the
Gl 581 system, which is already known to harbour a hot Neptune. One of
the planets has a mass of 5M_earth_ and resides at the "warm" edge
of the habitable zone of the star. It is thus the known exoplanet that
most resembles our own Earth. The other planet has a 7.7M_earth_
mass and orbits at 0.25AU from the star, close to the "cold" edge of
the habitable zone. These two new light planets around an M3 dwarf
further confirm the formerly tentative statistical trend toward (i)
many more very low-mass planets being found around M dwarfs than
around solar-type stars and (ii) low-mass planets outnumbering Jovian
planets around M dwarfs.
