    • A distance determination to the small Magellanic cloud with an accuracy of better than two percent based ... 
      Graczyk, Dariusz; Pietrzynski, Grzegorz; Thompson, Ian B.; Gieren, Wolfgang; Zgirski, Bartlomiej; Villanova, Sandro; Gorski, Marek; Wielgorski, Piotr; Karczmarek, Paulina; Narloch, Weronika; Pilecki, Bogumil; Taormina, Mónica; Smolec, Radoslaw; Suchomska, Ksenia; Gallenne, Alexandre; Nardetto, Nicolás; Storm, Jesper; Kudritzki, Rolf Peter; Kaluszynski, Mikolaj; Pych, Wojciech (IOP Publishing, 2020)
      We present a new study of late-type eclipsing binary stars in the Small Magellanic Cloud (SMC) undertaken with the aim of improving the distance determination to this important galaxy. A sample of 10 new detached, double-lined ...
    • Calibrating the surface brightness – color relation for late-type red giants stars in the visible domain ... 
      Nardetto, N.; Salsi, A.; Mourard, D.; Hocdé, V.; Perraut, K.; Gallenne, A.; Mérand, A.; Graczyk, D.; Pietrzynski, G.; Gieren, W.; Kervella, P.; Ligi, R.; Meilland, A.; Morand, F.; Stee, P.; Tallon-Bosc, I.; Brummelaar, T. ten (EDP Science, 2020)
      Context. The surface brightness - color relationship (SBCR) is a poweful tool for determining the angular diameter of stars from photometry. It was for instance used to derive the distance of eclipsing binaries in the Large ...
    • Hubble space telescope snapshot survey for resolved companions of galactic cepheids: final results 
      Evans, Nancy Remage; Günter, H. Moritz; Bond, Howard E.; Schaefer, Gail H.; Mason, Brian D.; Karovska, Margarita; Tingle, Evan; Wolk, Scott; Engle, Scott; Guinan, Edward; Pillitteri, Ignazio; Proffitt, Charles; Kervella, Pierre; Gallenne, Alexandre; Anderson, Richard I.; Moe, Maxwell (IOP Publishing, 2020)
      Cepheids in multiple systems provide information on the outcome of the formation of massive stars. They can also lead to exotic end-stage objects. This study concludes our survey of 70 galactic Cepheids using the Hubble ...
    • Multiplicity of Galactic Cepheids from long-baseline interferometry - III. Sub-percent limits on the relative ... 
      Gallenne, A.; Merand, A.; Kervella, Pierre; Monnier, J. D.; Schaefer, G. H.; Roettenbacher, R. M.; Gieren, W.; Pietrzynski, G.; McAlister, H.; ten Brummelaar, T.; Sturmann, J.; Sturmann, L.; Turner, N.; Anderson, R. I. (2016)
      We report new CHARA/Michigan InfraRed Combiner interferometric observations of the Cepheid archetype delta Cep, which aimed at detecting the newly discovered spectroscopic companion. We reached a maximum dynamic range Delta ...
    • Observational calibration of the projection factor of Cepheids II. Application to nine Cepheids with HST/FGS ... 
      Breitfelder, J.; Mérand, A.; Kervella, Pierre; Gallenne, A.; Szabados, L.; Anderson, R. I.; Le Bouquin, J.-B. (ESO, 2016-03)
      Context. The distance to pulsating stars is classically estimated using the parallax-of-pulsation (PoP) method, which combines spectroscopic radial velocity (RV) measurements and angular diameter (AD) estimates to derive ...
    • The Milky Way Cepheid Leavitt law based on Gaia DR2 parallaxes of companion stars and host open cluster populations 
      Breuval, Louise; Kervella, Pierre; Anderson, Richard; Riess, Adam G.; Arenou, Frédéric; Trahin, Boris; Mérand, Antoine; Gallenne, A.; Gieren, Wolfgang; Storm, J.; Bono, Giuseppe; Pietrzynski, Grzegorz; Nardetto, Nicolas; Javanmardi, Behnam; Hocde, Vincent (EDP Sciences, 2020)
      Aims. Classical Cepheids provide the foundation for the empirical extragalactic distance ladder. Milky Way Cepheids are the only stars in this class accessible to trigonometric parallax measurements. However, the parallaxes ...
