First stars X. The nature of three unevolved carbon-enhanced metal-poor stars

, 2006
International audienceContext: .On the order of 20% of the very metal-poor stars in the Galaxy exhibit large carbon enhancements. It is important to establish which astrophysical sites and processes are responsible for the elemental abundance patterns of

Probing the first generations of massive stars through fluorine in CEMP-no stars

The European Physical Journal A
We investigate whether the first discovered fluorine-rich CEMP-no star, CS 29498$-$043, can be explained by a very metal-poor rotating massive star. We consider single rotating stellar models of 20 $M_{\odot}$ at a metallicity of $Z = 10^{-5}$, exploring initial rotation rates from $\upsilon_{\rm ini}/\upsilon_{\rm crit} = 0$ to $0.7$ in increments of $

Detailed analyses of three neutron-capture-rich carbon-enhanced metal-poor stars

, 2009
International audienceApproximately 20% of very metal-poor stars ([Fe/H] 1.0). Such stars are referred to as carbon-enhanced metal-poor (CEMP) stars. We present a chemical abundance analysis based on high resolution spectra acquired with UVES at the VLT
