HST-STIS abundances in the uranium-rich very metal-poor star CS 31082-001

Barbuy, Beatriz Spite, Monique Hill, Vanessa

The abundance derivation of heavy r-elements may provide a better understanding of the r-process, and the determination of several reference r-elements should allow a better determination of the star's age. The spatial ultraviolet (UV) region presents a large number of lines of heavy elements, and in some cases such as Bi, Pt, Au, detectable...

HST/STIS abundances in the uranium rich metal poor star CS 31082-001: Constraints on the r-Process

Siqueira-Mello, C. Spite, M. Barbuy, B.

As a brief revision, the origin of heavy elements and the role of abundances in extremely metal-poor (EMP) stars are presented. Heavy element abundances in the EMP uranium-rich star CS 31082-001 based mainly on near-UV spectra from STIS/HST are presented. These results should be useful for a better characterisation of the neutron exposure(s)...
