Physics of Magnetic Stars
Special Astrophysical Observatory of the Russian Academy of Sciences
Nizhny Arkhyz

1-5 October, 2018
Magnetic fields of different magnitudes and topology are observed all over the Galaxy and play one of the most important roles in star formation and evolution. A conference was convened at the Special Astrophysical Observatory to discuss new findings in the studies of stellar magnetic fields. Particular emphasis was laid on chemically peculiar A and B main sequence stars, which have very strong fields and atmospheres of anomalous structure with inhomogeneous distribution of chemical elements over the surface. About 10 percent of A and B stars possess such fields, and we still do not know what caused their formation. The question can be solved by searching for regularities obtained in observations of magnetic A and B stars in different physical conditions: in young and old star clusters, in various regions of the Galaxy, among stars of different temperatures, fast or slowly rotating, single, binary, and multiple stars. These proceedings present measurements of stellar magnetic fields in the Orion OB1 association, new data on photometric and spectroscopic variability of magnetic and Herbig Ae/Be stars, studies of pulsations and other active phenomena in various stars, statistical studies, and theoretical problems discussed at the conference. This volume also describes ongoing projects to develop new instruments and software for analyzing observational data.
