Two new chemically peculiar stars with resolved, magnetically split lines.

Abstract (from CDS):

We report the discovery of resolved, magnetically split lines in two chemically peculiar stars, the SrEuCr star HD92499 and the Bp SiCr star HD157751. From FEROS spectra, we have measured a mean magnetic field modulus of 8.5kG for HD92499 and a mean magnetic field modulus of 6.6kG for HD157751. Both stars have small projected rotational velocities: vsini = 3.0 kms–1 and 8.5 kms–1, respectively. Our preliminary abundance analysis reveals an ionization imbalance of rare earths in HD92499, indicating the abundance pattern typical of rapidly oscillating Ap stars. Cr and Fe are found to be strongly overabundant in HD157751.
