The complex fossil magnetic field of the δscuti star HD 41641
Only three magnetic δScuti stars are known as of today. HD 41641 is a δScuti star showing chemical peculiarities and rotational modulation of its light curve, making it a good magnetic candidate. We acquired spectropolarimetric observations of this star with NARVAL at Télescope Bernard Lyot (TBL) to...
