The Pristine survey XIV: Uncovering the very metal-poor tail of the thin disc
2021
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticenter, spanning a wide range of metallicities from the extremely metal-poor regime ($\mathrm{[Fe/H]} -1.5$ dex. Furthermore, we detect signatures of a ''heated disc'', the so-called $Splash$, at metallicities higher than $\sim-1.5$ dex. Finally, at $\mathrm{[Fe/H]} < -1.5$ dex our anticenter sample is dominated by a kinematical halo with a net prograde motion.
