<br>
on Friday the 8th of October we will have an Astronomy seminar with Anke Arentsen from The University of Strasbourg speaking remotely via Zoom at 10:30.<br>
<br>
We also leave the Zoom session open after the questions, so that interested participants can stay and chat with the speaker in an informal way.<br>

<b>Title: </b><span style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13.3333px; text-size-adjust: auto;"><b>Galactic Archaeology with the oldest stars in the Milky Way</b><br>
<br>
Abstract: <span style="caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 13.3333px; text-size-adjust: auto;">The most metal-poor stars we find in the Milky Way today were born in pristine environments in the early Universe — these stars are expected
to be extremely old. 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.<span class="Apple-converted-space"> <br>
