Exploring the metal-poor inner Milky Way with the Pristine survey

Exploring the metal-poor inner Milky Way with the Pristine survey

Anke Arentsen (Strasbourg)

Old, metal-poor stars can teach us about the First Stars and about the early formation and evolution of the Milky Way. A prediction of simulations is that the fraction of metal-poor stars that are very old is highest towards the centres of galaxies: in their bulges. However, searching for metal-poor stars in the bulge region of the Milky Way faces many challenges, so much is unknown about the properties of the metal-poor inner Galaxy. In this talk, I will introduce the Pristine Inner Galaxy Survey (PIGS) which has reached unprecedented efficiency in finding very metal-poor stars in the Galactic bulge region. I will present recent PIGS results on the chemistry (focusing on carbon-enhanced metal-poor stars) and the kinematics of the metal-poor inner Galaxy, and discuss what they can teach us about this ancient component of the Milky Way. \;
