摘要
Magnetized stars usually exhibit periodic variations of the effective ( longitudinal) magnetic field Be caused by their rotation. We present a catalog of magnetic rotational phase curves, B-e vs. the rotational phase phi, and tables of their parameters for 136 stars on the main sequence and above it. Phase curves were obtained by the least squares fitting of sine wave or double wave functions to the available B-e measurements, which were compiled from the existing literature. Most of the catalogued objects are chemically peculiar A and B type stars ( 127 stars). For some stars we also improved or determined periods of their rotation. We discuss the distribution of parameters describing magnetic rotational phase curves in our sample.
