Magnetic field measurements of Ap stars. Discovery of a strong magnetic field in HD 18610.

STUETZ C., RYABCHIKOVA T. and WEISS W.W.

Abstract (from CDS):

HD 18610 was included in our project on abundance determination of rapidly oscillating (roAp) and non-oscillating (noAp) cool chemically peculiar stars. Already a preliminary investigation of the raw spectra indicated the presence of an intense magnetic field which was confirmed by a more detailed analysis. To determine the magnetic field strength we primarily used the Feii line at 6149.26Å, a strong line which is split in a anomalous Zeeman doublet. HD 18610 is a Cr-Eu-Sr non-pulsating Ap star with a Teff and logg typical for roAp stars. The classification of this star as a CP2 star (Preston, 1974ARA&A..12..257P) was confirmed with Δa photometry by Maitzen & Vogt (1983A&A...123...48M). In the present investigation we derived a mean magnetic field modulus of |B|=5700±200G.
