The blue-edge problem of the V1093 Her instability strip revisited using evolutionary models with atomic diffusion
S. Bloemen, Haili Hu, C. Aerts +5
We have computed a new grid of evolutionary subdwarf B star (sdB) models from the start of central He burning, taking into account atomic diffusion due to radiative levitation, gra…
On the use of the Fourier Transform to determine the projected rotational velocity of line-profile variable B stars
C. Aerts, S. Simon-Diaz, P. J. Groot +1
The Fourier Transform method is a popular tool to derive the rotational velocities of stars from their spectral line profiles. However, its domain of validity does not include line…
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…
Modelling of Sigma Scorpii, a high-mass binary with a Beta Cep variable primary component
A. Tkachenko, C. Aerts, K. Pavlovski +6
High-mass binary stars are known to show an unexplained discrepancy between the dynamical masses of the individual components and those predicted by models. In this work, we study…
