Dear all,

Tomorrows seminar has been cancelled. We are working on rescheduling the talk for the spring semester.

Best regards,

They can teach us about the First Stars and about the early formation and evolution of our Galaxy. In this talk I will focus on two groups of ancient stars: very metal-poor stars with exceptionally high carbon abundances (CEMP stars), which are probes of the nucleosynthesis in the First Stars and binary interactions, and the most metal-poor stars in the inner regions of the Milky Way. The fraction of metal-poor stars which are very old is expected to be very high in the Galactic bulge region. However, searching for metal-poor stars there faces many challenges, hence much is unknown about the properties of the metal-poor inner Galaxy. 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 and the kinematics of metal-poor inner Galaxy stars, and discuss what they can teach us about this ancient component of the Milky Way.
