Abstract

Context. CEMP-no stars are long-lived low-mass stars with a very low iron content, overabundances of carbon and no or minor signs for the presence of s- or r-elements. Although their origin is still a matter of debate, they are often considered as being made of a material ejected by a previous stellar generation (source stars).
Aims. We place constraints on the source stars from the observed abundance data of CEMP-no stars.
Methods. We computed source star models of 20, 32, and 60 M� at Z = 10
