      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 ...

    • 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 ...
    • VEGA/CHARA interferometric observations of Cepheids I. A resolved structure around the prototype classical ... 
      Nardetto, N.; Mérand, A.; Mourard, D.; Storm, J.; Gieren, W.; Fouqué, P.; Graczyk, D.; Kervella, P.; Neilson, H.; Pietrzynski, G.; Pilecki, B.; Breitfelder, J.; Berio, P.; Challouf, M.; Clausse, J.-M.; Ligi, R.; Mathias, P.; Meilland, A.; Perraut, K.; Poretti, E.; Rainer, M.; Spang, A.; Stee, P.; Tallon-Bosc, I.; Brummelaar, T. ten (EDP Sciences, 2016)
      Context. The B-W method is used to determine the distance of Cepheids and consists in combining the angular size variations of the star, as derived from infrared surface-brightness relations or interferometry, with its ...
