Detection of two extrasolar planets with the Kepler, HARPS-N and SOPHIE instruments
Two new extrasolar planets have been identified and characterized thanks to combined observations from the Kepler space telescope and the spectrographs SOPHIE and HARPS-N respectively mounted at the Observatoire de Haute-Provence (France) and the Telescopio Nazionale Galileo (Italy). These two planets are among the first ones detected with HARPS-N. The team that announced these planets obtained time on the Italian telescope through the OPTICON program that share nights of European telescopes between astronomers. These two new planets, called KOI-200b and KOI-889b, have about the size of Jupiter but are orbiting in less than 10 days on eccentric orbits. These new results help to understand the evolution of planets located very close to their star.
