Core formation and core composition from coupled geochemical and geophysical constraints
James Badro, Hélène Marie Piet
The formation of Earth's core left behind geophysical and geochemical signatures in both the core and mantle that remain to this day. Seismology requires that the core be lighter than pure iron and therefore must contain light elements, and the geochemistr ...
Natl Acad Sciences2015The CORALIE survey for southern extrasolar planets XVII. New and updated long period and massive planets
Context. Since 1998, a planet-search program around main sequence stars within 50 pc in the southern hemisphere has been carried out with the CORALIE echelle spectrograph at La Silla Observatory. Aims. With an observing time span of more than 14 years, the ...
Edp Sciences S A2013The structure of the asteroid 4 Vesta as revealed by models of planet-scale collisions
Asteroid 4 Vesta seems to be a major intact protoplanet, with a surface composition similar to that of the HED (howardite-eucrite-diogenite) meteorites(1-4). The southern hemisphere is dominated by a giant impact scar(5), but previous impact models(6-8) ha ...
Nature Publishing Group2013Extreme Deuterium Excesses in Ultracarbonaceous Micrometeorites from Central Antarctic Snow
Anders Meibom, François Robert
Primitive interplanetary dust is expected to contain the earliest solar system components, including minerals and organic matter. We have recovered, from central Antarctic snow, ultracarbonaceous micrometeorites whose organic matter contains extreme deuter ...
2010The CORALIE survey for southern extrasolar planets XVI. Discovery of a planetary system around HD 147018 and of two long period and massive planets orbiting HD 171238 and HD 204313
We report the detection of a double planetary system around HD 140718 as well as the discovery of two long period and massive planets orbiting HD 171238 and HD 204313. Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m E ...
