Strong magnetic fields of old white dwarfs are symmetric about the stellar rotation axes
S. Bagnulo, J. D. Landstreet
Many magnetic white dwarfs exhibit a polarised spectrum that periodically varies as the star rotates because the magnetic field is not symmetric about the rotation axis. In this wo…
Highly sensitive search for magnetic fields in white dwarfs using broad-band circular polarimetry
Andrei V. Berdyugin, Vilppu Piirola, Stefano Bagnulo +2
Circular polarisation measurements of white dwarfs of various ages and spectral types are useful to understand the origin and evolution of the magnetic field in degenerate stars. I…
BD-19 5044L: discovery of a short-period SB2 system with a magnetic Bp primary in the open cluster IC 4725
J. D. Landstreet, O. Kochukhov, E. Alecian +5
Until recently almost nothing was known about the evolution of magnetic fields found in upper main sequence Ap/Bp stars during their long main sequence lifetime. We are thus studyi…
HD 18078: A very slowly rotating Ap star with an unusual magnetic field structure
G. Mathys, I. I. Romanyuk, D. O. Kudryavtsev +3
Context. The existence of a significant population of Ap stars with very long rotation periods (up to several hundred years) has progressively emerged over the past two decades. Ho…
Magnetic fields and internal mixing of main sequence B stars
G. A. Wade, C. P. Folsom, J. Grunhut +2
We have obtained high-quality magnetic field measurements of 19 sharp-lined B-type stars with precisely-measured N/C abundance ratios. Our primary goal is to test the idea that a m…
The analysis of lithium in HD166473
A. V. Shavrina, V. Khalack, Y. Glagolevskij +4
The analysis of Li I 6708A line was performed for 6 rotational phases distributed over the whole rotational period (9.5 years) of HD166473. The magnetic field model was constructed…
