HE 0017+0055 : A probable pulsating CEMP-rs star and long-period binary
A. Jorissen, T. Hansen, S. Van Eck +6
A radial-velocity monitoring of the Carbon-Enhanced Metal-Poor (CEMP) star HE 0017+0055 over 8 years with the Nordic Optical Telescope and Mercator telescopes reveals variability w…
To Ba or not to Ba: Enrichment in s-process elements in binary systems with WD companions of various masses
T. Merle, A. Jorissen, S. Van Eck +2
The enrichment in s-process elements of barium stars is known to be due to pollution by mass transfer from a companion formerly on the thermally-pulsing asymptotic giant branch (AG…
Binary properties of CH and Carbon-Enhanced Metal-Poor stars
A. Jorissen, S. Van Eck, H. Van Winckel +8
The HERMES spectrograph installed on the 1.2-m Mercator telescope has been used to monitor the radial velocity of 13 low-metallicity carbon stars, among which 7 Carbon-Enhanced Met…
The Gaia-ESO Survey: Catalogue of H emission stars
Gregor Traven, Tomaž Zwitter, Sophie Van Eck +18
We discuss the properties of H emission stars across the sample of 22035 spectra from the Gaia-ESO Survey internal data release, observed with the GIRAFFE instrument and largely…
