Draco 119: A Remarkable Heavy Element-deficient Giant [PDF]

open access: yes, 2004
We report the abundance analysis of new high S/N spectra of the most metal-poor ([Fe/H] $= -2.95$) star presently known to be a member of a dwarf galaxy, the Draco dSph red giant, D119. No absorption lines for elements heavier than Ni are detected in two
