High-precision broadband linear polarimetry of early-type binaries. V. The Binary System HD 165052 in Open Cluster NGC 6530
Yasir Abdul Qadir, Andrei V. Berdyugin, Vilppu Piirola +3
This study continues our investigation of early-type binaries using high-precision broad-band polarimetry, focusing on HD 165052, a massive O+O-type binary in the young cluster NGC…
Searching for magnetic fields in featureless white dwarfs with the DIPOL-UF polarimeter at the Nordic Optical Telescope
A. Berdyugin, J. D. Landstreet, S. Bagnulo +2
About 20% of the white dwarfs possess a magnetic field that may be detected by the splitting and/or polarization of their spectral lines. As they cool, the effective temperatures o…
Discovery of magnetic fields in five DC white dwarfs
Andrei V. Berdyugin, Vilppu Piirola, Stefano Bagnulo +2
About half of white dwarfs (WDs) evolve to the DC state as they cool; the others become DQ or (temporarily?) DZ WDs. The recent magnetic survey of the local 20 pc volume has establ…
Maximum Entropy Limit of Small-scale Magnetic Field Fluctuations in the Quiet Sun
A. Y. Gorobets, S. V. Berdyugina, T. L. Riethmüller +12
The observed magnetic field on the solar surface is characterized by a very complex spatial and temporal behavior. Although feature-tracking algorithms have allowed us to deepen ou…
Markov properties of the magnetic field in the quiet solar photosphere
A. Y. Gorobets, J. M. Borrero, S. Berdyugina
The observed magnetic field on the solar surface is characterized by a very complex spatial and temporal behaviour. Although feature-tracking algorithms have allowed us to deepen o…
Magnetospherically driven optical and radio aurorae at the end of the stellar main sequence
G. Hallinan, S. P. Littlefair, G. Cotter +12
Aurorae are detected from all the magnetized planets in our Solar System, including Earth. They are powered by magnetospheric current systems that lead to the precipitation of ener…
