Discovery of the spectroscopic binary nature of three bright southern Cepheids
L. Szabados, R. I. Anderson, A. Derekas +4
We present an analysis of spectroscopic radial velocity and photometric data of three bright Galactic Cepheids: LR Trianguli Australis (LR TrA), RZ Velorum (RZ Vel), and BG Velorum…
Metal Abundances, Radial Velocities and other Physical Characteristics for the RR Lyrae Stars in the Kepler Field
James M. Nemec, Judith G. Cohen, Vincenzo Ripepi +5
Spectroscopic iron-to-hydrogen ratios, radial velocities, atmospheric parameters, and new photometric analyses are presented for 41 RR Lyrae stars (and one probable high-amplitude…
Discovery of the spectroscopic binary nature of six southern Cepheids
