12c/13c ratio and cno abundances in the classical very old metal-poor dwarf hd

HIGHLIGHTS

• who: Spite M. et al. from the GEPI, Observatoire de Paris, PSL Research University, CNRS, Place Jules Janssen, Meudon, France have published the paper: 12C/13C ratio and CNO abundances in the classical very old metal-poor dwarf HD, in the Journal: (JOURNAL)
• what: The aim of this work is to measure the precise abundances of carbon nitrogen oxygen and mainly the 12 C/13 C isotopic ratio in this very old metal-poor star to have good reference for the computations of the chemical evolution of the Galaxy. The authors interpolated an atmosphere model . . .
