Magnetic fields of HgMn stars
S. Hubrig, J. F. Gonzalez, I. Ilyin +8
The frequent presence of weak magnetic fields on the surface of spotted late-B stars with HgMn peculiarity in binary systems has been controversial during the two last decades. We…
Spectroscopic variability and magnetic fields of HgMn stars
S. Hubrig, J. F. Gonzalez, I. Ilyin +7
The discovery of exotic abundances, chemical inhomogeneities, and weak magnetic fields on the surface of late B-type primaries in spectroscopic binaries has important implications…
Bisectors of the HARPS Cross-Correlation-Function. The dependence on stellar atmospheric parameters
O. Basturk, T. H. Dall, R. Collet +2
Bisectors of the HARPS cross-correlation function (CCF) can discern between planetary radial-velocity (RV) signals and spurious RV signals from stellar magnetic activity variations…
Visualization and spectral synthesis of rotationally distorted stars
T. H. Dall, L. Sbordone
Simple spherical, non-rotating stellar models are inadequate when describing real stars in the limit of very fast rotation: Both the observable spectrum and the geometrical shape o…
Oscillations and magnetic fields in the G8 star EK Eridani
T. H. Dall, M. Cunha, K. G. Strassmeier +2
Asteroseismology can provide information that is otherwise not easily accessible, like the stellar mass and the evolutionary stage. Strong magnetic fields are usually accompanied b…
Solar-like oscillations and magnetic activity of the slow rotator EK Eri
T. H. Dall, H. Bruntt, D. Stello +1
We aim to understand the interplay between non-radial oscillations and stellar magnetic activity and test the feasibility of doing asteroseismology of magnetically active stars. We…
