Li-rich K giants, dust excess, and binarity
A. Jorissen, H. Van Winckel, L. Siess +3
The origin of the Li-rich K giants is still highly debated. Here, we investigate the incidence of binarity among this family from a nine-year radial-velocity monitoring of a sample…
Binary evolution along the Red Giant Branch with BINSTAR: The barium star perspective
Ana Escorza, Lionel Siess, Hans Van Winckel +1
Barium (Ba), CH, and extrinsic or Tc-poor S-type stars are evolved low- and intermediate-mass stars that show enhancement of slow-neutron-capture-process elements on their surface,…
Recipes for bolometric corrections and Gaia luminosities of B-type stars: Application to an asteroseismic sample
May G. Pedersen, Ana Escorza, Peter I. Papics +1
We provide three statistical model prescriptions for the bolometric corrections appropriate for B-type stars as a function of: 1) T_eff, 2) T_eff, log g, and 3) T_eff, log g, [M/H]…
Discovery of technetium- and niobium-rich S stars: the case for bitrinsic stars
S. Shetye, S. Van Eck, S. Goriely +4
S stars are late-type giants with overabundances of s-process elements. They come in two flavours depending on the presence or not of technetium (Tc), an element without stable iso…
Spectroscopic orbits of three dwarf barium stars
P. L. North, A. Jorissen, A. Escorza +2
Barium stars are thought to result from binary evolution in systems wide enough to allow the more massive component to reach the asymptotic giant branch and eventually become a CO…
Barium & related stars and their white-dwarf companions I. Giant stars
A. Jorissen, H. M. J. Boffin, D. Karinkuzhi +4
This paper provides long-period and revised orbits for barium and S stars adding to previously published ones. The sample of barium stars with strong anomalies comprise all such st…
