Discovery of the magnetic field in the pulsating B star beta Cephei
H. F. Henrichs, J. A. de Jong, E. Verdugo +17
Although the star itself is not He enriched, the periodicity and the variability in the UV wind lines of the pulsating B1 IV star beta Cep are similar to what is observed in magnet…
The cross helicity at the solar surface by simulations and observations
G. Ruediger, M. Kueker, R. S. Schnerr
The quasilinear mean-field theory for driven MHD turbulence leads to the result that the observed cross helicity <u \cdot b> may directly yield the magnetic eddy diffusivity η_{T}…
Dimming of the 17th Century Sun
Peter Foukal, Ada Ortiz, Roald Schnerr
Reconstructions of total solar irradiance (TSI) rely mainly on linear relations between TSI variation and indices of facular area. When these are extrapolated to the prolonged 15th…
Radio observations of candidate magnetic O stars
R. S. Schnerr, K. L. J. Rygl, A. J. van der Horst +5
Context: Some O stars are suspected to have to have (weak) magnetic fields because of the observed cyclical variability in their UV wind-lines. However, direct detections of these…
Stokes imaging polarimetry using image restoration: A calibration strategy for Fabry-Pérot based instruments
R. S. Schnerr, J. de la Cruz Rodriguez, M. van Noort
context: The combination of image restoration and a Fabry-Pérot interferometer (FPI) based instrument in solar observations results in specific calibration issues. FPIs generally s…
The brightness of magnetic field concentrations in the quiet Sun
R. S. Schnerr, H. C. Spruit
In addition to the `facular' brightening of active regions, the quiet Sun also contains a small scale magnetic field with associated brightenings in continuum radiation. We measure…
