The gamma Dor CoRoT target HD49434. I-Results from the ground-based campaign
K. Uytterhoeven, P. Mathias, E. Poretti +22
Context: We present the results of an extensive ground-based photometric and spectroscopic campaign on the gamma Dor CoRoT target HD49434. This campaign was preparatory to the CoRo…
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…
Asteroseismology and Interferometry
M. S. Cunha, C. Aerts, J. Christensen-Dalsgaard +22
Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies…
