Lithium-6 : Evolution from Big Bang to Present
Elisabeth Vangioni-Flam, Michel Casse, Roger Cayrel +3
The primordial abundances of Deuterium, he4, and li7 are crucial to determination of the baryon density of the Universe in the framework of standard Big Bang nucleosynthesis (BBN).…
On-line determination of stellar atmospheric parameters Teff, log g, [Fe/H] from ELODIE echelle spectra. II - The library of F5 to K7 stars
C. Soubiran, D. Katz, R. Cayrel
A library of 211 echelle spectra taken with ELODIE at the Observatoire de Haute-Provence is presented. It provides a set of spectroscopic standards covering the full range of gravi…
On-line determination of stellar atmospheric parameters Teff, log g, [Fe/H] from ELODIE echelle spectra. I - The method
D. Katz, C. Soubiran, R. Cayrel +2
We present a method estimating the atmospheric parameters Teff, log g, [Fe/H] for stars observed, even at low signal to noise ratio, with the echelle spectrograph ELODIE on the 193…
