Determination of stellar rotation with Gaia and effects of spectral mismatch
A. Gomboc, D. Katz
Stellar spectra obtained with Radial Velocity Spectrometer on-board Gaia will enable determination of projected rotational velocities (v sin i) from rotational broadening of spectr…

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…

Effective temperatures from A5 to G5 spectral types, using Balmer line profiles
C. van 't Veer-Menneret, C. Bentolila, D. Katz
We show how previous works (Fuhrmann et al., van 't Veer-Menneret & Megessier) demonstrate the efficiency of the use of Balmer line profiles for effective temperature determination…
