“…Magnetic stars show a well-defined tendency to concentrate in the central region of association. No significant differences are found between the field strength in the Bp type stars of the association and Bp type field stars(Romanyuk et al 2013).…”

“…Like in the case of HD 6757, the magnetic field of HD 40759 was discovered by Kudryavtsev et al [22]. Later this star was included in a spectropolarimetric survey of stars in the Orion OB1 association as HD 40759 is a known member of its subgroup c [28]. During the full period of observation, we have collected more than ten individual measurements of B l , although the period of its variability remains unclear.…”

A strong and stable magnetic field covering the whole surface is a landmark of chemically peculiar or CP stars. To explain the origin of mag- netic stars, several hypotheses were proposed, which depending on the mech- anism and time of formation can be grouped into three main. The magnetic field may originate in the protostellar medium (“fossil field”), turbulent layers of a star (“dynamo” mechanism) or in the other environment. In either scenario, binary stars appear as a merit of its reliability. Recent advances in observational astrophysics uncovered a bunch of new binary magnetic stars that were considered as rare before. We outline the results of studies of exotic binary and multiple systems with magnetic CP components: HD 6757, HD 34736, and HD 40759.

“…Using the catalog of Renson & Manfroid (), we found a total of 85 CP stars of various types among the 814 members of the association (see details in Romanyuk et al ). The average frequency of CP stars in the Orion OB1 association is 10.4%, which is generally the same as for the all known CP stars.…”

“…Most of the known Ap stars (70%) are field stars and their ages are poorly known, while most of the known Bp stars (75%) are cluster members with well‐determined ages (Romanyuk et al ). Observations of magnetic CP stars in open clusters of different ages are the best way to study the formation and evolution of these objects.…”

We discuss an ongoing project on the investigation of magnetic fields of chemically peculiar (CP) stars in the Orion OB1 association. More than 500 polarized spectra for 55 stars have been obtained with the Russian 6‐m telescope. We found eight new magnetic stars in addition to the 20 previously known. The frequency of Ap/Bp stars among normal A and B stars and the frequency of magnetic stars among all Ap/Bp stars decrease with age in the Orion OB1 association.
