Abstract

We present a literature survey of about a hundred papers concerned with “Magnetic fields and physical parameters of chemically peculiar and related stars” published mainly in 2017. We considered instrumental and methodical issues, gave first results obtained with the high-resolution PEPSI spectropolarimeter, described new programs for data reduction and analysis. New magnetic chemically peculiar stars in the Orion association were discovered, weak (of the order of one Gauss) magnetic fields were found in stars of other types. The first attempt was made to detect extragalactic magnetic stars.Magnetic fieldmaps and maps of element distribution over the surfaces of stars of different types were constructed, evolution of spots on cool stars was found. New magnetic, spectroscopic, and photometric data have been obtained for magnetic white dwarfs and degenerate stars of other types.
