Title: Abundance analysis and magnetic fields measurements in a few Herbig Ae stars Authors: S. Hubrig, C. R. Cowley, M. Schoeller, I. Ilyin, G. Lo Curto, M. Petr-Gotzens Abstract: We present the most recent abundance analysis of a few Herbig Ae stars based on high-resolution UVES and HARPS spectra. The determination of their magnetic fields is carried out using HARPSpol spectra.
