VLT/FLAMES spectroscopy of red giant branch stars in the Carina dwarf spheroidal galaxy

Context. The ages of individual red giant branch stars can range from 1 Gyr old to the age of the Universe, and it is believed that the abundances of most chemical elements in their photospheres remain unchanged with time (those that are not affected by the first dredge-up). This means that they tra...
