We reconsidered the previous studies of properties of magnetic stars based on the latest data on average surface magnetic fields of 177 stars. New, corrected results have been obtained that allow a better understanding of the phenomenon of magnetic chemically peculiar stars.

Secular Stability of the Magnetic Structures of Magnetic Stars. II
Numerous indications that the magnetic field structures in magnetic stars do not change with age are cited. The stars rotate like a solid.
Remarks on Difference of Properties of Am and Ap Stars
We performed the comparative analysis of the properties of Ap and Am stars. It is shown that the main differences in the formation and evolution of these objects are due to the influence of a
Characteristics of Magnetic Star Formation at the Early Stages of Evolution
Abstract —The results of works dedicated to the study of the early stages of evolution of magnetic and non-magnetic chemically peculiar stars are discussed. The fossil hypothesis of the formation of
Remarks on the Properties of the Magnetic Field of the Star HD37776
Studies of the magnetic field and its structure in the star HD37776 by various authors are discussed. Significant conflicts among these results are noted which suggest that the star has not been
Secular Stability of Magnetic Field Structures in Magnetic CP-Stars
The magnetic field structures of stars with different ages are studied. No changes in the position and orientation of magnetic dipoles with age are observed. It is concluded that there are no global
Evolutionary Features and Other Characteristics of Magnetic Stars with Helium Anomalies (He-r, He-w)
Abstract —We critically review the results of earlier studies on magnetic stars with anomalous helium lines. We discuss the issues associated with the fossil-field theory and the scenario of the
Magnetic Fields of Chemically Peculiar and Related Stars. VI. Main Results of 2019 and Near-Future Prospects
We present a review of the papers written in the field of stellar magnetism studies in 2020. More than 70 original papers related to different areas of the specified scientific topics have been
Benchmarking the fundamental parameters of Ap stars with optical long-baseline interferometric measurements
Context. The variety of physical processes at play in chemically peculiar stars makes it difficult to determine their fundamental parameters. In particular, for the magnetic ones, called Ap stars,
