The constant magnetic field of [xi]1 CMa: geometry or slow rotation?

The constant magnetic field of [xi]1 CMa: geometry or slow rotation?

Abstract We report recent observations of the sharp-lined magnetic [beta]Cep pulsator ξ1 CMa (= HD 46328). The longitudinal magnetic field of this star is detected consistently, but it is not observed to vary significantly, during nearly 5 years of observation. In this poster we evaluate whether the...

Zusammenfassung:Abstract We report recent observations of the sharp-lined magnetic [beta]Cep pulsator ξ1 CMa (= HD 46328). The longitudinal magnetic field of this star is detected consistently, but it is not observed to vary significantly, during nearly 5 years of observation. In this poster we evaluate whether the constant longitudinal field is due to intrinsically slow rotation, or rather if the stellar or magnetic geometry is responsible. [PUBLICATION ABSTRACT]
