TL;DR: In this paper, the HARPS spectrograph was used to obtain 121 new radial velocity measurements of Gl 581 with the ESO 3.6 m telescope, and analyzed those together with previous 119 measurements of that star to examine these potential additional super-Earth planets.

Transiting exoplanets from the CoRoT space mission VI. CoRoT-Exo-3b: The first secure inhabitant of the brown-dwarf desert
TL;DR: In this paper, the discovery and characterization of the first very massive transiting planetary companion with a short orbital period is reported, which is the most intriguing transiting substellar object discovered so far.

Hubble Space Telescope times-series photometry of the planetary transit of HD189733: no moon, no rings, starspots
Frederic Pont,R. L. Gilliland,C. Moutou,François Bouchy,Timothy M. Brown,D. Charbonneau,M. Mayor,D. Queloz,N. C. Santos,Stéphane Udry +9 more
TL;DR: In this article, three transits of the giant gas planet around the nearby K dwarf HD 189733 with the ACS camera on the Hubble Space Telescope were monitored, and the resulting very high accuracy lightcurve (signal-to-noise ratio near 15000 on individual measurements, 35000 on 10-minute averages) allows a direct geometric measurement of the orbital inclination, radius ratio and scale of the system.

The HARPS search for southern extra-solar planets. X. A m sin i = 11 Mearth planet around the nearby spotted M dwarf GJ 674
X. Bonfils,M. Mayor,X. Delfosse,T. Forveille,M. Gillon,C. Perrier,Stéphane Udry,François Bouchy,C. Lovis,Francesco Pepe,D. Queloz,N. C. Santos,J. L. Bertaux +12 more
TL;DR: In this article, the authors used a 2-planar Keplerian model to detect a new Neptune-mass planet, GJ 674b, around a M2.5-dwarf.

TL;DR: In this article, the discovery of a very light planetary companion to the star mu Ara (HD160691) was presented, with a semi-amplitude of 4.1 m/s, the smallest Doppler amplitude detected so far.
