The HARPS search for southern extra-solar planets XXXIV. Occurrence, mass distribution and orbital properties of super-Earths and Neptune-mass planets ?

TL;DR: In this paper, the results of an 8-year survey carried out at the La Silla Observatory with the HARPS spectrograph to detect and characterize planets in the super-Earth and Neptune mass regime were reported.
Journal ArticleDOI

The HARPS search for southern extra-solar planets. XIII. A planetary system with 3 Super-Earths (4.2, 6.9, & 9.2 Earth masses)

TL;DR: In this paper, a planetary system with three super-Earths orbiting a K2V metal-deficient star at a distance of only 13 parsec was detected by the HARPS GTO high-precision planet-search programme.
Journal ArticleDOI

The HARPS search for southern extra-solar planets. X. A m sin i = 11 Mearth planet around the nearby spotted M dwarf GJ 674

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.
Journal ArticleDOI

Shape model, reference system definition, and cartographic mapping standards for comet 67P/Churyumov-Gerasimenko Stereo-photogrammetric analysis of Rosetta/OSIRIS image data

TL;DR: In this article, the authors used stereo-photogrammetric methods (SPG) to analyze the rotational elements of 67P and derived a volume for the northern hemisphere of 9.35 km3 ± 0.1 km3.
Journal ArticleDOI

Images of Asteroid 21 Lutetia: A Remnant Planetesimal from the Early Solar System

- 28 Oct 2011 - 
TL;DR: A spacecraft flyby of an asteroid reveals a high-density body that is more like a planetesimal than a rubble pile, which contrasts with smaller asteroids visited by previous spacecraft, which are probably shattered bodies, fragments of larger parents, or reaccumulated rubble piles.
