摘要：

The material used to form the CEMP-no stars presents signatures of processing by the CNO cycle and by He-burning from a previous stellar generation called spinstars. We compare the composition of the ejecta (wind + supernova) of a spinstar model to observed abundances of CEMP-no stars. We show that observed abundances as well as the isotope ratio C-12/C-13 may be reproduced by the spinstar ejecta if we assume different mass cuts when adding the supernova material to the wind ejecta.
