The ELODIE survey for northern extra – solar planets ⋆ ⋆ ⋆ I . 6 new extra – solar planet candidates
Precise radial–velocity observations at Haute–Provence Observatory (OHP, France) with the ELODIE echelle spectrograph have been undertaken since 1994. In addition to several discoveries described elsewhere, including and following that of 51 Peg b, they reveal new sub–stellar companions with essentially moderate to long periods. We report here about such companions orbiting five solar–type star...
Almost half of the stellar systems in the solar neighborhood are made up of multiple stars. In multiple-star systems, planet formation is under the dynamical influence of stellar companions, and the planet occurrence rate is expected to be different from that for single stars. There have been numerous studies on the planet occurrence rate of single star systems. However, to fully understand pla...
Aims. We present the results of a deep imaging survey of stars surrounded by planets detected through the radial velocity technique. The purpose is to search for and to characterize long-period stellar and substellar companions. The sample contains a total of 26 stars, among which 6 exhibit additional radial velocity drifts. Methods. We used NACO, at the ESO Very Large Telescope, and PUEO-KIR, ...
Since the first modern humans left their birthplace in Eastern Africa and slowly spread to populate every inhabitable place on the planet, Homo sapiens has been a migratory animal. Over thousands of years, these travellers unknowingly carried excess baggage on their journeys: countless microbes in and on their bodies, which evolved along with their host. By applying the tools of modern genomics...
In the context of abstract coinduction in complete lattices, the notion of compatible function makes it possible to introduce enhancements of the coinduction proof principle. The largest compatible function, called the companion, subsumes most enhancements and has been proved to enjoy many good properties. Here we move to universal coalgebra, where the corresponding notion is that of a final di...
The imagination and creativity of children is often puzzling to the adult mind. Pretend play and make-believe friends are often prevalent in the life of a child. Past research shows a relationship between the use of the imagination in children’s play and their social, cognitive, and emotional development. Furthermore, there are a number of gender differences in the type of imaginary play and pr...
