The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
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…
Non-LTE Effects in Berylium Abundances
T. P. Idiart, F. Thevenin
In this work we analyze the beryllium-iron chemical diagram from the point of view of non-LTE effects. Be abundances were re-calculated by considering non-LTE corrections in ioniza…
