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…
Updated results on prototype chalcogenide fibers for 10-um wavefront spatial filtering
P. Borde, G. Perrin, A. Amy-Klein +2
The detection of terrestrial planets by Darwin/TPF missions will require extremely high quality wavefronts. Single-mode fibers have proven to be powerful beam cleaning components i…
Rationale for the use of color information on Eddington
P. Borde, A. Leger, D. Rouan +1
For the Eddington mission, the intrinsic stellar variability can be a major source of noise in the detection of extrasolar planets by the transit method. We derive that most detect…
Exo-planet detection with the COROT space mission. I. A multi-transit detection criterion
Pascal Borde', Daniel Rouan, Alain Leger
We present a detection criterion for exo-planets to be used with the space mission COROT. This criterion is based on the transit method, which suggests the observation of star dimm…
