 rich stars - Anke Ardern-Arentsen / IoA

DESCRIPTION:The oldest\, most metal-poor stars we find in the Milky Way to
 day were born in pristine environments in the early Universe. These local\
 , ancient stars contain unique clues about the First Stars and the early f
 ormation and evolution of our Galaxy. At low metallicity\, many stars have
  been found to be enhanced in carbon\, coming in two main types: some cont
 ain the fingerprints of the First Stars and others have experienced binary
  interaction with an evolved companion. I recently built a homogeneous sam
 ple of C-rich metal-poor stars using the Gaia XP spectra\, employing a neu
 ral network and a dedicated training sample. I will present this recent pa
 per and discuss how the change in frequency of C-rich stars with Galactic 
 environment relates to globular clusters and clustered star formation in t
 he early Universe.
