    • 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 ...
    • 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 ...
