The discovery of a planetary candidate around the evolved low-mass Kepler giant star HD 175370
M. Hrudková, A. Hatzes, R. Karjalainen +20
We report on the discovery of a planetary companion candidate with a minimum mass Msini = 4.6 M_J orbiting the K2 III giant star HD 175370 (KIC 007940959). This star was a target i…
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…
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…
Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign
P. G. Beck, E. Kambe, M. Hillen +35
Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…
Discovery of binarity, spectroscopic frequency analysis, and mode identification of the delta Sct star 4CVn
V. S. Schmid, N. Themeßl, M. Breger +12
More than 40 years of ground-based photometric observations of the delta Sct star 4CVn revealed 18 independent oscillation frequencies, including radial as well as non-radial p-mod…
