Extreme r-process Enhanced Stars at High Metallicity in Fornax*
Research output: Contribution to journal › Journal article › Research › peer-review
We present and discuss three extremely r-process enhanced stars located in the massive dwarf spheroidal galaxy Fornax. These stars are very unique with an extreme Eu enrichment (1.25 1) at high metallicities (i.e., [Fe/H] greater than or similar to -1.5). The stellar abundance pattern contains Lu, observed for the first time in a dwarf galaxy, and reveals that a late burst of star formation has facilitated extreme r-process enhancement late in the galaxy's history (
