Vetting Galactic Leavitt Law Calibrators using Radial Velocities: On the Variability, Binarity, and Possible Parallax Error of 19 Long-period Cepheids
R. I. Anderson, S. Casertano, A. G. Riess +9
We investigate the radial velocity (RV) variability and spectroscopic binarity of 19 Galactic long-period ( d) classical Cepheid variable stars whose trig…
G 207-9 and LP 133-144: light curve analysis and asteroseismology of two ZZ Ceti stars
Zs. Bognár, M. Paparó, L. Molnár +4
G 207-9 and LP 133-144 are two rarely observed ZZ Ceti stars located in the middle and close to the blue edge of the ZZ Ceti instability domain, respectively. We aimed to observe t…
Stellar modelling of Spica, a high-mass spectroscopic binary with a beta Cep variable primary component
A. Tkachenko, J. M. Matthews, C. Aerts +16
Binary stars provide a valuable test of stellar structure and evolution, because the masses of the individual stellar components can be derived with high accuracy and in a model-in…
Kepler's first view of O-star variability: K2 data of five O stars in Campaign 0 as a proof-of-concept for O-star asteroseismology
B. Buysschaert, C. Aerts, S. Bloemen +9
We present high-precision photometric light curves of five O-type stars observed with the refurbished {\it Kepler\/} satellite during its Campaign 0. For one of the stars, we also…
Gravity-mode period spacings as seismic diagnostic for a sample of gamma Doradus stars from Kepler space photometry and high-resolution ground-based spectroscopy
T. Van Reeth, A. Tkachenko, C. Aerts +20
Gamma Doradus stars (hereafter gamma Dor stars) are gravity-mode pulsators of spectral type A or F. Such modes probe the deep stellar interior, offering a detailed fingerprint of t…
Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
C. Aerts, S. Simon-Diaz, C. Catala +16
{We aim to detect and interpret photometric and spectroscopic variability of the bright CoRoT B-type supergiant target HD\,46769 (). We also attempt to detect a magnetic fi…
HD 50844: the new look of Delta Sct stars from CoRoT space photometry
E. Poretti, E. Michel, R. Garrido +21
It has also been suggested that the detection of a wealth of very low amplitude modes in Delta Sct stars was only a matter of signal--to--noise ratio. Access to this treasure, impo…
