Ingalls,Emeline Bolmont,Jérémy Leconte,Sean N. Raymond,Franck Selsis,Martin Turbet,Khalid Barkaoui,Adam J. Burgasser,Matthew R. Burleigh,Sean Carey,Aleksander Chaushev,Chris M. Copperwheat,Laetitia Delrez,Catarina S. Fernandes,Daniel Luke Holdsworth,Enrico J. Kotze,Valérie Van Grootel,Y. Almleaky,Zouhair Benkhaldoun,Pierre Magain,Didier Queloz +29 more
TL;DR: The observations reveal that at least seven planets with sizes and masses similar to those of Earth revolve around TRAPPIST-1, and the six inner planets form a near-resonant chain, such that their orbital periods are near-ratios of small integers.
Journal ArticleDOI

Xavier Bonfils,X. Delfosse,Stéphane Udry,T. Forveille,Michel Mayor,C. Perrier,François Bouchy,Michaël Gillon,Christophe Lovis,Francesco Pepe,Didier Queloz,Nuno C. Santos,Damien Ségransan,Jean-Loup Bertaux +13 more
TL;DR: In this paper, the authors used a fraction of the guaranteed time on the ESO/HARPS spectrograph to estimate the radial velocities of 102 southern nearby M dwarfs, and then applied systematic searches for long-term trends, periodic signals, and Keplerian orbits.
Journal ArticleDOI

TL;DR: In this paper, the authors reported the discovery of very shallow (ΔF/F ≈ 3.4× 10 −4 ) periodic dips in the light curve of an active V = 11.7 G9V star observed by the CoRoT satellite, which they interpret as caused by a transiting companion.
