Context. Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron produced by the slow neutron-capture process (s process). These stars belong to binary systems in which the primary star evolved through the asymptotic giant branch (AGB) phase. During this phase the primary star produced s-process elements and transferred them onto the secondary, which is now observed as a Ba star. Aims. We compare the largest homogeneous set of Ba giant star observations of the s… Expand

Rubidium in Barium stars
Barium (Ba) stars are chemically peculiar stars that display in their atmospheres signatures of the slow neutron-capture (s-process) mechanism that operates within asymptotic giant branch (AGB)Expand
Characterizing the companion AGBs using surface chemical composition of barium stars
Barium stars are one of the important probes to understand the origin and evolution of slow neutron-capture process elements in the Galaxy. These are extrinsic stars, where the observed s-processExpand
Barium and related stars, and their white-dwarf companions
Context. Barium and S stars without technetium are red giants and are suspected of being members of binary systems due to their overabundances in heavy elements. These elements are produced by theExpand
Heavy elements in barium stars
New elemental abundances for the neutron-capture elements Sr, Nb, Mo, Ru, La, Sm, and Eu are presented for a large sample of 180 barium (Ba) giant stars, a class of chemically peculiar objects thatExpand
The s-process enriched star HD 55496: origin from a globular cluster or from the tidal disruption of a dwarf galaxy?
We present a new abundance analysis of HD 55496, previously known as a metal-poor barium star. We found that HD 55496 has a metallicity [Fe/H]  = −1.55 and is s-process enriched. We find that HDExpand

Rocky asteroids and planets display nucleosynthetic isotope variations that are attributed to the heterogeneous distribution of stardust from different stellar sources in the solar protoplanetaryExpand
The formation of barium giants via mass accretion in binary systems
We examine the composition of barium stars in the context of mass transfer from an asymptotic giant branch (AGB) companion. We accrete between 0.01 and 0.5 M⊙ of AGB ejecta on to low mass companionsExpand
Discovery of s-process enhanced stars in the LAMOST survey

The Origin of Elements from Carbon to Uranium
To reach a deeper understanding of the origin of elements in the periodic table, we construct Galactic chemical evolution (GCE) models for all stable elements from C (A=12) to U (A=238) from firstExpand
Probing the Nucleosynthetic Contribution of Low-metallicity, Low-mass Star Companions of CEMP Stars

s-Process nucleosynthesis in carbon stars
We present the first detailed and homogeneous analysis of the s-element content in Galactic carbon stars of N type. Abundances of Sr, Y, Zr (low-mass s-elements, or ls), Ba, La, Nd, Sm, and CeExpand
When binaries keep track of recent nucleosynthesis
Context. Barium stars are s-process enriched giants. They owe their chemical peculiarities to a past mass transfer phase. During this phase they were polluted by their binary companion, which at theExpand

Discovery of three lead-rich stars
Analysis shows that three metal-poor stars are more enriched in lead than in any other element heavier than iron, and excellent agreement between the observed and predicted abundances reinforces current understanding of the detailed operation of the s-process deep in the interiors of AGB stars.
