We present the Pristine survey, a new narrow-band photometric survey focused on the
metallicity-sensitive Ca H&K lines and conducted in the Northern hemisphere with the wide …

The Pristine survey is a narrow-band, photometric survey focused around the wavelength
region of the Ca ii H&K absorption lines, designed to efficiently search for extremely metal …

The early Universe presented a star formation environment that was almost devoid of heavy
elements. The lowest metallicity stars thus provide a unique window into the earliest Galactic …

▪ Abstract We discuss the importance of very metal-poor stars to develop an understanding
of the nature of the first stars that formed in the Universe and the nucleosynthesis events …

The chemical abundances of large samples of extremely metal-poor (EMP) stars can be
used to investigate metal-free stellar populations, supernovae, and nucleosynthesis as well …

We present and discuss the results of a search for extremely metal-poor stars based on
photometry from data release DR1. 1 of the SkyMapper imaging survey of the southern sky …

The Pristine survey uses narrow-band photometry to derive precise metallicities down to the
extremely metal-poor regime (), and currently consists of over 4 million FGK-type stars over a …

I review the status of the search for extremely metal-poor halo stars with the Hamburg/ESO
objective-prism survey (HES). 2194 candidate metal-poor turn-off stars and 6133 giants in …

We present a detailed abundance analysis based on high-resolution and high signal-to-
noise spectra of eight extremely metal-poor (EMP) stars with [\mathrm {Fe}\,/\mathrm …

ABSTRACT A chemo-dynamical analysis of 115 metal-poor candidate stars selected from
the narrow-band Pristine photometric survey is presented based on CFHT high-resolution …
