High resolution spectroscopy for Cepheids distance determination. III. A relation between gamma-velocities and gamma-asymmetries
N. Nardetto, A. Stoekl, D. Bersier +1
Galactic Cepheids in the vicinity of the Sun have a residual line-of-sight velocity, or gamma-velocity, which shows a systematic blueshift of about 2 km/s compared to an axisymmetr…

High resolution spectroscopy for Cepheids distance determination. II. A period- projection factor relation
N. Nardetto, D. Mourard, Ph. Mathias +2
The projection factor is a key quantity for the interferometric Baade-Wesselink (hereafter IBW) and surface-brightness (hereafter SB) methods of determining the distance of Cepheid…

High resolution spectroscopy for Cepheids distance determination. I. Line asymmetry
N. Nardetto, D. Mourard, P. Kervella +3
The ratio of pulsation to radial velocity (the projection factor) is currently limiting the accuracy of the interferometric Baade-Wesselink method. This work aims at establishing a…
