2016IBVS.6174....1H - IAU Inform. Bull. Var. Stars, 6174, 1 (2016/June-0)
Confirmation of the magnetic nature of the delta Scuti star HD 21190.
HUBRIG S. and SCHOLLER M.
Abstract (from CDS):
HD 21190 is a known delta Scuti star showing Ap star characteristics and a variability period of 3.6h discovered by the Hipparcos mission. Our previous spectropolarimetric observations with FORS1 at the VLT showed the presence of a rather weak magnetic field of the order of a few tens of Gauss. New spectropolarimetric measurements with FORS2 at the VLT reveal that the magnetic field in this star is much stronger, about -250G, indicating that also Ap stars can pulsate in the delta Scuti range.
