A long period model for the magnetic star γ Equulei.

LEROY J.L., BAGNULO S., LANDOLFI M. and LANDI DEGL'INNOCENTI E.

Abstract (from CDS):

Linear polarimetry has enabled us to observe the rotation of the magnetic axis of the star γ Equ (nearly 15deg over the period 1990-1993). Thus, the very long rotation period of more than 70 years, suggested by previous authors, is now confirmed in a straightforward way. We propose numerical values for the various parameters which enter the oblique rotator model and we show that they are consistent with all the available data on the magnetism of γ Equ.
