The review highlights the diversity of magnetic field behaviors in stars

Abstract

Actually there exist 218 stars with measured phase curves of the longitudinal (effective) magnetic field B_e. In that group 172 objects are classified as magnetic chemically peculiar stars (mCP). Remaining objects are stars of various spectral types, from the most massive hot Of? supergiants to low mass red dwarfs and stars with planets. This paper aims to review briefly properties of the observed magnetic field in various types of stars.
