    • Investigating Cepheid l Carinae' s cycle-to-cycle variations via contemporaneous velocimetry and ... 
      Anderson, R. I.; Mérand, A.; Kervella, Pierre; Breitfelder, J.; Le Bouquin, J. B.; Eyer, L.; Gallenne, A.; Palaversa, L.; Semaan, T.; Saesen, S.; Mowlavi, N. (Oxford University Press, 2016)
      Baade-Wesselink-type (BW) techniques enable geometric distance measurements of Cepheid variable stars in the Galaxy and the Magellanic clouds. The leading uncertainties involved concern projection factors required to ...
    • Masses and age of the chemically peculiar double-lined binary 
      Le Bouquin, J. B.; Beust, H.; Duvert, G.; Berger, J. P.; Ménard, Francois; Zins, G. (EDP Sciences, 2013)
      Aims.We aim at measuring the stellar parameters of the two chemically peculiar components of the B9.5Vp HgMn + A2 Vm doublelined spectroscopic binary HD141556 ( Lup), whose period is 15:25 days. Methods. We combined ...
    • 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 ...
    • Sculpting the disk around T Chamaeleontis: an interferometric view 
      Olofsson, J.; Benisty, Myriam; Le Bouquin, J. B.; Berger, J. P; Lacour, S.; Ménard, Francois; Henning, Thomas; Crida, A.; Burtscher, L.; Meeus, G.; Ratzka, T.; Pinte, Christophe; Augereau, J. C.; Malbet, F.; Lazare, B.; Traub, W. (EDP Sciences, 2013)
      Context. Circumstellar disks are believed to be the birthplace of planets and are expected to dissipate on a timescale of a few Myr. The processes responsible for the removal of the dust and gas will strongly modify the ...
    • The GRAVITY young stellar object survey VI. Mapping the variable inner disk of HD 163296 at sub-au scales 
      Sánchez Bermúdez, J.; Garatti, Caratti; García López, R.; Perraut, K.; Labadie, L.; Benisty, Myriam; Brandner, W.; Dougados, C.; García, P. J.; Henning, Th.; Klarmann, L.; Amorim, A.; Bauboeck, M.; Berger, J. P.; Le Bouquin, J. B.; Caselli, P.; Clenet, Y.; Du Foresto, V. Coude; De Zeeuw, P. T.; Drescher, A.; Duvert, G.; Eckart, A.; Eisenhauer, F.; Filho, M.; Gao, F.; Gendron, E.; Genzel, R.; Gillessen, S.; Grellmann, R.; Heissel, G.; Horrobin, M.; Hubert, Z.; Jiménez Rosales, A.; Jocou, L.; Kervella, P.; Lacour, S.; Lapeyrere, V.; Lena, P.; Ott, T.; Paumard, T.; Perrin, G.; Shimizu, T.; Stadler, J.; Straub, O.; Straubmeier, C.; Sturm, E.; van Dishoeck, E.; Vincent, F.; von Fellenberg, S. D.; Widmann, F.; Woillez, J. (EDP Sciences, 2021)
      Context. Protoplanetary disks drive some of the formation process (e.g., accretion, gas dissipation, formation of structures) of stars and planets. Understanding such physical processes is one of the most significant ...
    • The GRAVITY young stellar object survey: IV. The CO overtone emission in 51 Oph at sub-au scales 
      Koutoulaki, M.; García López, R.; Natta, A.; Fedriani, R.; Garatti, A. Caratti O.; Ray, T. P.; Coffey, D.; Brandner, W.; Dougados, C.; García, P. J.

(EDP Sciences, 2021)
      Context. 51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 mu m, most likely originating in the innermost regions of a circumstellar disc.Aims. We aim to obtain the physical ...
    • The VLTI/PIONIER near-infrared interferometric survey of southern T Tauri stars
