Metal-poor stars observed with the Magellan Telescope – IV. Neutron-capture element signatures in 27 main-sequence stars

Metal-poor stars observed with the Magellan Telescope – IV. Neutron-capture element signatures in 27 main-sequence stars

ABSTRACT We present a chemo-dynamical analysis for 27 near main-sequence turnoff metal-poor stars, including 20 stars analysed for the first time. The sample spans a range in [Fe/H] from −2.5 to −3.6, with 44 per cent having [Fe/H]
