Lanthanides and other spectral oddities in a Centauri
C. R. Cowley, S. Hubrig, J. F. Gonzalez
Context: There is considerable interest in the helium variable a Cen as a bridge between helium-weak and helium-strong CP stars. Aims: We investigate Ce III and other possible lant…
Abundances in the Herbig Ae star HD 101412: Abundance anomalies; Lambda Boo-Vega characteristics?
C. R. Cowley, S. Hubrig, J. F. González +1
Context: Recent attention has been directed to abundance variations among very young stars. Aims: To perform a detailed abundance study of the Herbig Ae star HD 101412, taking adva…
Dynamical evolution of titanium, strontium, and yttrium spots on the surface of the HgMn star HD 11753
M. Briquet, H. Korhonen, J. F. Gonzalez +2
Aims. We gathered about 100 high-resolution spectra of three typical HgMn (mercury-manganese) stars, HD 11753, HD 53244, and HD 221507, to search for slowly pulsating B-like pulsat…
The exceptional Herbig Ae star HD101412: The first detection of resolved magnetically split lines and the presence of chemical spots in a Herbig star
S. Hubrig, M. Schoeller, I. Savanov +5
We obtained high-resolution, high signal-to-noise UVES and a few lower quality HARPS spectra revealing the presence of resolved magnetically split lines. HD101412 is the first Herb…
AO Vel: The role of multiplicity in the development of chemical peculiarities in late B-type stars
J. F. González, S. Hubrig, F. Castelli
We present high-resolution, high signal-to-noise UVES spectra of AO Vel, a quadruple system containing an eclipsing BpSi star. From these observations we reconstruct the spectra of…
