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 class=""></span></span><br class=""><div class="">Tine Libbrecht is inviting you to a scheduled Zoom meeting.</div><div class=""><br class=""></div><div class="">Topic: Friday Seminar</div><div class="">Time: Oct 8, 2021 10:15 AM Stockholm</div><div class=""><br class=""></div><div class="">Join Zoom Meeting</div><div class=""><a href="https://stockholmuniversity.zoom.us/j/4181744735?pwd=WlcrNnZpUmVva05seHA4d1ZOUitBUT09" class="">https://stockholmuniversity.zoom.us/j/4181744735?pwd=WlcrNnZpUmVva05seHA4d1ZOUitBUT09</a></div><div class=""><br class=""></div><div class="">Meeting ID: 418 174 4735</div><div class="">Passcode: wevRIEA38a</div></span></font></div></div></blockquote></div><br class=""></div></body></html>
