The Hipparcos HR diagram of nearby stars in the metallicity range -1.0 < [Fe/H] < 0.3
Y. Lebreton, M. -N. Perrin, R. Cayrel +2
From an initial sample of a few hundred stars selected for an Hipparcos program, a subsample of 33 objects with direct determination of their effective temperature, bolometric magn…

New high S/N observations of the Li-6/Li-7 blend in HD 84937 and two other metal-poor stars
R. Cayrel, M. Spite, F. Spite +3
High S/N ratio spectra have been obtained at CFHT at a spectral resolution of 100 000 for HD 84397 and two other metal poor stars. For HD 84 937, the S/N of 650 per pixel was obtai…

Survival of 6li and 7li in Metal-Poor Stars
R. Cayrel, Y. Lebtreton, P. Morel
The relationship between the respective depletion factors for 6Li and 7Li in metal-poor stars is studied for two simple models of depletion by nuclear burning by mixing with deeper…
