Search for the magnetic field of the O7.5 III star xi Persei
H. F. Henrichs, R. S. Schnerr, J. A. de Jong +3
Cyclical wind variability is an ubiquitous but as yet unexplained feature among OB stars. The O7.5 III(n)((f)) star xi Persei is the brightest representative of this class on the N…
The magnetic field of the B3V star 16 Pegasi
H. F. Henrichs, C. Neiner, R. S. Schnerr +8
The Slowly Pulsating B3V star 16 Pegasi was discovered by Hubrig (2006) to be magnetic, based on low-resolution spectropolarimetric observations with FORS1 at the VLT. We have conf…
A study of the magnetic field in the photospheric and circumstellar components of Herbig Ae stars
S. Hubrig, M. A. Pogodin, R. V. Yudin +2
We intend to investigate separately the photospheric and circumstellar (CS) magnetic field components in seven Herbig Ae stars. The study is based on low-resolution (R ~ 2000 and 4…
On the H emission from the Cephei system
R. S. Schnerr, H. F. Henrichs, R. D. Oudmaijer +1
Be stars, which are characterised by intermittent emission in their hydrogen lines, are known to be fast rotators. This fast rotation is a requirement for the formation of a Kepler…
Radio observations of candidate magnetic O stars
R. S. Schnerr, K. L. J. Rygl, A. J. van der Horst +3
A number of O stars are suspected to have (weak) magnetic fields because of the observed cyclical variability in their UV wind-lines. However, direct detections of these magnetic f…
Magnetic fields and UV-line variability in Cephei
R. S. Schnerr, H. F. Henrichs, S. P. Owocki +2
We present results of numerical simulations of wind variability in the magnetic B1 IVe star Cephei. 2D-MHD simulations are used to determine the structure of the wind. From the…
