Metallicity of M dwarfs II. A comparative study of photometric metallicity scales
V. Neves, X. Bonfils, N. C. Santos +6
Stellar parameters are not easily derived from M dwarf spectra, which are dominated by complex bands of diatomic and triatomic molecules and not well described at the line by line…
The HARPS search for southern extra-solar planets XXXII. Only 4 planets in the Gl~581 system
T. Forveille, X. Bonfils, X. Delfosse +14
The Gl 581 planetary system has generated wide interest, because its 4 planets include both the lowest mass planet known around a main sequence star other than the Sun and the firs…
A short-period super-Earth orbiting the M2.5 dwarf GJ3634. Detection with Harps velocimetry and transit search with Spitzer photometry
X. Bonfils, M. Gillon, T. Forveille +12
We report on the detection of GJ3634b, a super-Earth of mass m sin i = 7.0 +/-0.9 Mearth and period P = 2.64561 +/- 0.00066 day. Its host star is a M2.5 dwarf, has a mass of 0.45+/…
Metallicity of M dwarfs: the link to exoplanets
V. Neves, X. Bonfils, N. C. Santos
The determination of the stellar parameters of M dwarfs is of prime importance in the fields of galactic, stellar and planetary astronomy. M stars are the least studied galactic co…
