Gregor Traven,Tomaz Zwitter,S. Van Eck,A. Klutsch,Rosaria Bonito,Rosaria Bonito,A. C. Lanzafame,A. C. Lanzafame,Emilio J. Alfaro,Amelia Bayo,Angela Bragaglia,M. T. Costado,Francesco Damiani,Ettore Flaccomio,Antonio Frasca,A. Hourihane,F. M. Jiménez-Esteban,F. M. Jiménez-Esteban,Carmela Lardo,L. Morbidelli,Elena Pancino,Elena Pancino,Loredana Prisinzano,G. G. Sacco,Clare Worley +24 more
TL;DR: In this article, the properties of Hα emission stars across the sample of 22035 spectra from the Gaia-ESO Survey internal data release, observed with the GIRAFFE instrument and largely belonging to stars in young open clusters.

Paula Jofre,Paula Jofre,Gregor Traven,Keith Hawkins,Gerard Gilmore,Jason L. Sanders,Thomas Mädler,Matthias Steinmetz,Andrea Kunder,Georges Kordopatis,Paul J. McMillan,Olivier Bienaymé,Joss Bland-Hawthorn,Brad K. Gibson,Eva K. Grebel,Ulisse Munari,Julio F. Navarro,Quentin A. Parker,Warren A. Reid,Warren A. Reid,George M. Seabroke,Tomaž Zwitter +21 more
TL;DR: In this article, the authors apply the twin method to determine parallaxes to 232 545 stars of the RAVE survey using the parallaus of Gaia DR1 as a reference.
Journal ArticleDOI

Thibault Merle,M. Van der Swaelmen,S. Van Eck,Alain Jorissen,R. J. Jackson,Gregor Traven,Tomaz Zwitter,Dimitri Pourbaix,A. Klutsch,G. G. Sacco,R. Blomme,Thomas Masseron,Gerard Gilmore,Sofia Randich,C. Badenes,Amelia Bayo,Thomas Bensby,Maria Bergemann,K. Biazzo,Francesco Damiani,D. Feuillet,Antonio Frasca,Anais Gonneau,R. D. Jeffries,Paula Jofre,L. Morbidelli,Nami Mowlavi,Elena Pancino,L. Prisinzano +28 more
TL;DR: In this paper, a statistical χ 2 -test is performed on spectra of the Gaia-ESO Survey internal data release 5 (GES iDR5) to identify and characterise SBs with one visible component (SB1s) in fields covering mainly the discs, the bulge, the CoRot fields, and some stellar clusters and associations.
