Line identification in the Ca II K spectral region of sharp-lined B-type stars.

Abstract (from CDS):

Previous CaII K observations of the B-type star HD 83206 have revealed putative high-velocity interstellar clouds (HVCs) at Local Standard of Rest (LSR) velocities of -80 and -110km/s. Similar results were also found for the sightline towards HD135485. In this article, we show that these absorption lines are in fact due to stellar SII features. As the CaII K absorption line in B-type stars is often used to assess the presence and distance of HVCs, we also present a very high quality spectrum of HD 83206 in the CaII K region (~±4Å or ±300km/s), so that in the future confusion between stellar lines and HVC features may be avoided.
