Title: Xenon in Mercury-Manganese Stars Authors: M. M. Dworetsky, J. L. Persaud, K. Patel Previous studies of elemental abundances in Mercury-Manganese (HgMn) stars have occasionally reported the presence of lines of the ionised rare noble gas Xe II, especially in a few of the hottest stars with...
Title: Spots on the surface of HgMn stars: Clues to the origin of Hg and Mn peculiarities Authors: S. Hubrig, J.F. Gonzalez, R. Arlt The important result achieved in our recent study of a large sample of HgMn stars using UVES at the VLT and FEROS at the ESO 2.2m telescope is the finding that most HgMn star...
Title: A refined analysis of the remarkable Bp star HR 6000 Authors: F. Castelli, S. Hubrig UVES spectra of the very young (~10^7 years) peculiar B-type star HR 6000 were analysed in the near-UV and visual spectral regions (3050-9460 A) with the aim to extend to other spectral ranges the study made pr...
