The first stars: a classification of CEMP-no stars [PDF]

open access: yesAstronomy and Astrophysics, 2015
Aims. We propose and apply a new classification for the CEMP–no stars, which are carbon-enhanced metal-poor stars with no overabundance of s-elements and with [Fe/H] generally ≤−2.5. Methods.

The first stars: CEMP-no stars and signatures of spinstars [PDF]

open access: yesAstronomy and Astrophysics, 2015
Aims. The CEMP-no stars are “carbon-enhanced-metal-poor” stars that in principle show no evidence of s- and r-elements from neutron captures. We try to understand the origin and nucleosynthetic site of their peculiar CNO, Ne–Na, and Mg–Al abundances.

A NEW CEMP-s RR LYRAE STAR [PDF]

open access: yesAstrophysical Journal Letters, 2012
We show that SDSS J170733.93+585059.7 (hereafter SDSS J1707+58), previously identified by Aoki and collaborators as a carbon-enhanced metal-poor star (with s-process-element enhancements; CEMP-s), on the assumption that it is a main-sequence turn-off star, is the RR Lyrae star VIII-14 identified by the Lick Astrograph Survey.

Chemodynamically Tagged Groups of CEMP Stars in the Halo of the Milky Way. I. Untangling the Origins of CEMP-s and CEMP-no Stars

open access: yesAstrophysical Journal, 2023
We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars with abundance analyses based on moderate- to high-resolution spectroscopic studies.
