On the incidence of magnetic fields in slowly pulsating B, β Cephei and B-type emission-line stars
On the incidence of magnetic fields in slowly pulsating B, β Cephei and B-type emission-line stars
We have obtained 40 high-resolution circular spectropolarimetric measurements of 12 slowly-pulsating B (SPB) stars, 8 Beta Cephei stars and two Be stars with the ESPaDOnS and NARVAL spectropolarimeters. The aim of these observations is to evaluate recent claims of a high incidence of magnetic field detections in stars of these …
