Magnetic field variations with a rotational period on solar-like star ξ Bootis A.

PLACHINDA S.I. and TARASOVA T.N.

Abstract (from CDS):

We examine the global configuration of the magnetic field of the active dwarf ξ Boo A as a function of stellar rotation phase (P=6.1455±0.0003 days), using direct high-precision spectropolarimetric measurements. The magnetic field varies from -10 G up to +30 G. Integrated magnetic flux on the surface changes polarity during a single rotation period on ξ Boo A, resulting in a flux ratio of ΔΦ+/ΔΦ–∼1.5. This is the first study of the general magnetic field as a function of rotation on a solar-like star other than the Sun.
