The HARPS search for southern extra-solar planets - VI. A Neptune-mass planet around the nearby M dwarf Gl 581
- X. Bonfils, T. Forveille, +7 authors J. Bertaux
- Physics
- 8 September 2005
We report the discovery of a Neptune-mass planet around Gl 581 (M3V, M = 0.31 ), based on precise Doppler measurements with the HARPS spectrograph at La Silla Observatory. The radial velocities… Expand
The HARPS survey for southern extra-solar planets. II. A 14 Earth-masses exoplanet around μ Arae
- N. Santos, F. Bouchy, +13 authors S. Vauclair
- Physics
- 25 August 2004
In this letter we present the discovery of a very light planetary companion to the star mu Ara (HD160691). The planet orbits its host once every 9.5days, and induces a sinusoidal radial velocity… Expand
The HARPS search for southern extra-solar planets - XIX. Characterization and dynamics of the GJ 876 planetary system
- A. Correia, J. Couetdic, +11 authors S. Udry
- Physics
- 26 January 2010
Precise radial-velocity measurements for data acquired with the HARPS spectrograph infer that three planets orbit the M4 dwarf star GJ876. In particular, we confirm the existence of planet d, which… Expand
The HARPS search for southern extra-solar planets. XIII. A planetary system with 3 Super-Earths (4
- M. Mayor, S. Udry, +7 authors D. S'egransan
- Physics
- 27 June 2008
Received ; accepted To be inserted later Abstract. This paper reports on the detection of a planetary system with three Super-Earths orbiting HD 40307. HD 40307 is a K2 V metal-deficient star at a… Expand
Martian dayglow as seen by the SPICAM UV spectrograph on Mars Express
- F. Leblanc, J. Chaufray, J. Lilensten, O. Witasse, J. Bertaux
- Physics
- 1 September 2006
[1] In this paper we describe measurements of the Martian dayglow obtained by SPICAM UV spectrograph on board Mars Express between October 2004 and March 2005. Typical spectra (of more than 24,000… Expand
The HARPS search for southern extra-solar planets. X. A m sin i = 11 M_â planet around the nearby spotted M dwarf GJ 674
- X. Bonfils, M. Mayor, +10 authors J. Bertaux
- Physics
- 2 April 2007
Context. How planet properties depend on stellar mass is a key diagnostic of planetary formation mechanisms. Aims. This motivates planet searches around stars that are significantly more massive or… Expand
The HARPS search for southern extra-solar planets. VIII. μ Arae , a system with four planets
- F. Pepe, A. Correia, +13 authors S. Udry
- Physics
- 18 August 2006
Context. The µ Arae planetary system is fairly complex, because it contains two already known planets, µ Arae b with P = 640 days and µ Arae c with P = 9.64 days , and a third companion on a wide,… Expand
The HARPS search for southern extra-solar planets - XXVIII. Up to seven planets orbiting HD 10180: probing the architecture of low-mass planetary systems
- C. Lovis, D. S'egransan, +11 authors N. Santos
- Physics
- 23 November 2010
Low-mass extrasolar planets are presently being discovered at an increased pace by radial velocity and transit surveys, which opens a new window on planetary systems. Aims. We are conducting a… Expand
Spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from the OSIRIS instrument onboard the ROSETTA spacecraft
- S. Fornasier, P. Hasselmann, +51 authors J. Vincent
- Physics
- 26 May 2015
The Rosetta mission of the European Space Agency has been orbiting the comet 67P/Churyumov-Gerasimenko (67P) since August 2014 and is now in its escort phase. A large complement of scientific… Expand
WATER PRODUCTION BY COMET 103P/HARTLEY 2 OBSERVED WITH THE SWAN INSTRUMENT ON THE SOHO SPACECRAFT

- Physics
- 26 April 2011
Global water production rates were determined from the Lyα emission of hydrogen around comet 103P/Hartley 2, observed with the SWAN (Solar Wind Anisotropies) all-sky camera on the SOHO spacecraft… Expand
