On the rotation of the chemically peculiar magnetic star 56 Arietis.

ADELMAN S.J., MALANUSHENKO V., RYABCHIKOVA T.A. and SAVANOV I.

Abstract (from CDS):

This study used extensive sets of phase resolved photometric and spectroscopic data obtained by the authors and supplemented by that from the literature to investigate the light and equivalent width variations of the mCP star 56 Ari. Its rotational period is found to be increasing at a rate of about 2s per 100 years. In addition there is evidence for a second period whose length is about 5 years which is attributed to the precession of the axis of rotation.
