TL;DR
This paper discusses the ESO Large Programme that used UVES at the VLT to obtain high-resolution spectra of extremely metal-poor stars, aiming to understand the properties of the first stars in the universe.
Contribution
It presents the main results from a large observational campaign targeting extremely metal-poor stars to study the early universe's stellar populations.
Findings
High-resolution spectra of EMP stars obtained
Insights into the chemical composition of the first stars
Advancement in understanding early stellar evolution
Abstract
In ESO period 65 (April-September 2000) the large programme 165.N-0276, led by Roger Cayrel, began making use of UVES at the Kueyen VLT telescope. Known within the Team and outside as ``First Stars'', it was aimed at obtaining high resolution, high signal-to-noise ratio spectra in the range 320 nm -- 1000 nm for a large sample of extremely metal-poor (EMP) stars identified from the HK objective prism survey.In this contribution we highlight the main results of the large programme.
