Internal rotation of red giants by asteroseismology
M. P. Di Mauro, D. Cardini, R. Ventura +12
We present an asteroseismic approach to study the dynamics of the stellar interior in red-giant stars by asteroseismic inversion of the splittings induced by the stellar rotation o…
Low-frequency variations of unknown origin in the Kepler Delta Scuti star KIC 5988140 = HD 188774
P. Lampens, A. Tkachenko, H. Lehmann +9
We used high-quality Kepler photometry and spectroscopic data to investigate the Kepler binary candidate KIC 5988140. Using the spectrum synthesis method, we derived the fundamenta…
Detection of gravity modes in the massive binary V380 Cyg from Kepler spacebased photometry and high-resolution spectroscopy
A. Tkachenko, C. Aerts, K. Pavlovski +17
We report the discovery of low-amplitude gravity-mode oscillations in the massive binary star V380 Cyg, from 180 d of Kepler custom-aperture space photometry and 5 months of high-r…
Gravito-inertial and pressure modes detected in the B3 IV CoRoT target HD 43317
P. I. Pápics, M. Briquet, A. Baglin +14
Context. OB stars are important building blocks of the Universe, but we have only a limited sample of them well understood enough from an asteroseismological point of view to provi…
