    • 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 ...
    • Mass and p-factor of the type II cepheid OGLE-LMC-T2CEP-098 in a Binary System 
      Pilecki, Bogumil; Gieren, Wolfgang; Smolec, Radoslaw; Pietrzynski, Grzegorz; Thompson, Ian B.; Anderson, Richard I.; Bono, Giuseppe; Soszynski, Igor; Kervella, Pierre; Nardetto, Nicolás; Taormina, Mónica; Stepien, Kazimierz; Wielgorski, Piotr (IOP Publishing, 2017)
      We present the results of a study of the type II Cepheid (P-puls = 4.974 days) in the eclipsing binary system OGLELMC- T2CEP-098 (P-orb = 397.2 days). The Cepheid belongs to the peculiar W Vir group, for which the evolutionary ...
    • 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 ...
