Magnetic field variations with pulsational phase in the classical Cepheid star η Aquilae.

PLACHINDA S.I.

Abstract (from CDS):

The presence of the magnetic field on the classical Cepheid η Aquilae is established. The magnetic field shows periodic variations with a reversal of its polarity due to stellar pulsations (-100<Be<+50G). Two closed values of Be lie out of the magnetic curve at phases φ=0.610 and φ=0.629. It was suggested that these recoiled points show that the abrupt change of the magnetic field occurred at the phase of propagation of the shock wave within the stellar atmosphere.
