Magnetic field of the roAp star KIC~10685175: observations versus theory

Fangfei Shi, Huawei Zhang, Swetlana Hubrig +5

KIC 10685175 is a roAp star whose polar magnetic field is predicted to be 6 kG through a non-adiabatic axisymmetric pulsation theoretical model. In this work, we aim to measure the…

The rapidly oscillating Ap star gamma Equ: linear polarization as an enhanced pulsation diagnostic?

S. Hubrig, S. P. Jarvinen, I. Ilyin +2

We present the first short time scale observations of the roAp star gamma Equ in linear polarized light obtained with the PEPSI polarimeter installed at the LBT. These observations…

Magnetic field geometry and magnetospheric environment of the strongly magnetic Of?p star NGC 1624-2

S. P. Järvinen, S. Hubrig, M. Schöller +3

NGC 1624-2 is an O7f?p star with a reported probable polar magnetic field strength 20 kG, which is the strongest magnetic field ever measured in an O-type star. We study the…

The search for magnetic fields in two Wolf-Rayet stars and the discovery of a variable magnetic field in WR55

S. Hubrig, M. Schöller, A. Cikota +1

Magnetic fields in Wolf-Rayet (WR) stars are not well explored, although there is indirect evidence, e.g. from spectral variability and X-ray emission, that magnetic fields should…

The anomalous atmospheric structure of the strongly magnetic Ap star HD166473

S. P. Järvinen, S. Hubrig, G. Mathys +3

High resolution spectropolarimetric observations of the strongly magnetic, super-slowly rotating rapidly oscillating Ap star HD166473 are used to investigate the implications of th…

The near-infrared companion to HD94660 (=KQ Vel)

M. Schöller, C. A. Hummel, S. Hubrig +4

The Bp star HD94660 is a single-lined spectroscopic binary. Some authors have suggested that the unseen companion of at least 2M_sun may be a compact object. We intend to study thi…
