Discovery of Resolved Magnetically Split Lines in SDSS/APOGEE Spectra of 157 Ap/Bp Stars
S. Drew Chojnowski, Swetlana Hubrig, Sten Hasselquist +7
We report on magnetic field measurements of 157 chemically peculiar A/B stars (Ap/Bp) based on resolved, magnetically split absorption lines present in -band spectra provided by…
HD66051, an eclipsing binary hosting a highly peculiar, HgMn-related star
Ewa Niemczura, Stefan Hümmerich, Fiorella Castelli +4
HD66051 is an eclipsing system with an orbital period of about 4.75 d that exhibits out-of-eclipse variability with the same period. New multicolour photometric observations confir…
New H-band Stellar Spectral Libraries for the SDSS-III/APOGEE survey
O. Zamora, D. A. Garcia-Hernandez, C. Allende Prieto +18
The Sloan Digital Sky Survey--III (SDSS--III) Apache Point Observatory Galactic Evolution Experiment (APOGEE) has obtained high resolution (R 22,500), high signal-to-noise r…
Wavelengths and oscillator strengths of Xe II from the UVES spectra of four HgMn stars
K. Yüce, F. Castelli, S. Hubrig
In spite of large overabundances of Xe II observed in numerous mercury-manganese (HgMn) stars, Xe II oscillator strengths are only available for a very limited number of transition…
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…
On the metallicity gradient of the Galactic disk
S. Pedicelli, G. Bono, B. Lemasle +15
Aims: The iron abundance gradient in the Galactic stellar disk provides fundamental constraints on the chemical evolution of this important Galaxy component. However the spread aro…
