We have shown that this star was ejected from the metal-poor outer rim of the Galaxy in a binary super- or hypernova. The star provides a unique opportunity to study the chemical composition of SN/HN ejecta, because nuclear-processed debris was deposited onto its surface in the course of the explosion. From optical spectra we have already demonstrated that the signature of the explosion is visible in its atmospheric abundance pattern, because the alpha-elements are enhanced. Our aim is to derive abundances for a large number of chemical elements, which are accessible only in the UV spectral range, to constrain the nucleosynthesis in the SN/HN in detail. If we succeed to detect tale-telling signatures of r-process elements in the UV spectrum, we may finally pin down the long-sought site of the r-process. ------------------------------------------------------------------------------------ Observations Description ------------------------ Full spectral coverage of the NUV and FUV is required to achieve science goals, targeting as high S/N as possible in the STIS abd COS ranges. Target is rotating at about 120 km/s, post-observation binning can be applied to increase S/N.
