HE2159-0551: a very metal-poor peculiar low Ba giant -- a candidate from the LMS-1/Wukong
A. Schichtel, D. H. Plonka, C. J. Hansen
We present a comprehensive spectroscopic and kinematic analysis of the very metal-poor ([Fe/H] = -2.60 0.20 dex) giant star HE2159-0551. By investigating the star's chemodyna…

Modeling the progenitors of low-mass post-accretion binaries
A. J. Dimoff, R. J. Stancliffe, C. J. Hansen +2
About half of the mass of all heavy elements with mass number A > 90 is formed through the slow neutron capture process (s-process), occurring in evolved asymptotic giant branch (A…
