Modeling of Alpha Cen and Procyon using VLTI observations
P. Kervella, F. Thevenin, P. Morel +4
We present a novel approach to model the nearby stars Alpha Cen A & B and Procyon A using asteroseismic and interferometric constraints. Using the VINCI instrument installed at the…
VINCI / VLTI observations of Main Sequence stars
P. Kervella, F. Thevenin, P. Morel +7
Main Sequence (MS) stars are by far the most numerous class in the Universe. They are often somewhat neglected as they are relatively quiet objects (but exceptions exist), though t…
The diameters of Alpha Centauri A and B - A comparison of the asteroseismic and VINCI/VLTI views
P. Kervella, F. Thevenin, D. Segransan +4
We compare the first direct angular diameter measurements obtained on our closest stellar neighbour, Alpha Centauri, to recent model diameters constrained by asteroseismic observat…
