Detailed homogeneous abundance studies of 14 Galactic s-process enriched post-AGB stars: In search of lead (Pb)
Kenneth De Smedt, Hans Van Winckel, Devika Kamath +4
This paper is part of a larger project in which we systematically study the chemical abundances of Galactic and extragalactic post-asymptotic giant branch (post-AGB) stars. Lead (P…
The HERMES Solar Atlas and the spectroscopic analysis of the seismic solar analogue KIC3241581
P. G. Beck, C. Allende Prieto, T. Van Reeth +7
Solar-analog stars provide an excellent opportunity to study the Sun's evolution, i.e. the changes with time in stellar structure, activity, or rotation for solar-like stars. The u…
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…
Post-AGB stars in the Magellanic Clouds and neutron-capture processes in AGB stars
M. Lugaro, S. W. Campbell, H. Van Winckel +3
We explore modifications to the current scenario for the slow neutron capture process in asymptotic giant branch (AGB) stars to account for the Pb deficiency observed in post-AGB s…
