    • Benchmark stars for Gaia Fundamental properties of the Population II star HD 140283 from interferometric, ... 
      Creevey, O.; Thévenin, F.; Berio, P.; Heiter, U.; Von Braun, K.; Mourard, D.; Bigot, L.; Boyajian, T.; Kervella, Pierre; Morel, P.; Pichon, B.; Chiavassa, A.; Nardetto, N.; Perraut, K.; Meilland, A.; Mc Alister, H.; ten Brummelaar, T.; Farrington, C.; Sturmann, J.; Sturmann, L.; Turner, N. (EDP Sciences, 2015)
      Metal-poor halo stars are important astrophysical laboratories that allow us to unravel details about many aspects of astrophysics, including the chemical conditions at the formation of our Galaxy, understanding the processes ...
    • Cepheid distances from the SpectroPhoto-Interferometry of Pulsating Stars (SPIPS) Application to the ... 
      Mérand, A.; Kervella, Pierre; Breitfelder, J.; Gallenne, A.; Coudé du Foresto, V.; Brummelaar, T. A. ten; McAlister, H. A.; Ridgway, S.; Sturmann, L.; Sturmann, J.; Turner, N. H. (EDP Sciences, 2015)
      Context. The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface brightness technique, is an elegant method to determine distances of pulsating stars in a quasi-geometrical ...
    • Robust high-contrast companion detection from interferometric observations. The CANDID algorithm and an ... 
      Gallenne, A.; Mérand, A.; Kervella, Pierre; Monnier, J. D.; Schaefer, G. H.; Baron, F.; Breitfelder, J.; Le Bouquin, J. B.; Roettenbacher, R. M.; Gieren, W.; Pietrzynski, G.; McAlister, H.; Brummelaar, T. ten; Sturmann, J.; Sturmann, L.; Turner, N.; Ridgway, S.; Kraus, S. (EDP Sciences, 2015)
      Context. Long-baseline interferometry is an important technique to spatially resolve binary or multiple systems in close orbits. By combining several telescopes together and spectrally dispersing the light, it is possible ...
