Bertrand Mennesson,Guy Perrin,G. Chagnon,V. Coudé du Foresto,S. T. Ridgway,Antoine Mérand,P. Salomé,P. Bordé,W. D. Cotton,Sebastien Morel,Pierre Kervella,Wesley A. Traub,Marc G. Lacasse +12 more
TL;DR: In this article, the authors proposed a two-component model consisting of a warm (1500-2000 K), extended (up to 3 stellar radii), optically thin (� ’ 0:5) layer located above the classical photosphere.
Journal ArticleDOI
The diameter and evolutionary state of Procyon A. Multi-technique modeling using asteroseismic and interferometric constraints
TL;DR: In this paper, the angular diameter of Procyon A (aCMiA, F5IV-V) was measured with the VINCI/VLTI instrument with a relative precision of 0.9% using the CESAM code.
Journal ArticleDOI
The interferometric diameter and internal structure of Sirius A
TL;DR: In this article, the angular diameter of the bright star Sirius A with the VINCI/VLTI instrument was obtained, and the authors derived internal structure models corresponding to ages between 200 and 250 12 Myr.
Journal ArticleDOI
The interferometric diameter and internal structure of Sirius A
TL;DR: In this article, the angular diameter of the bright star Sirius A with the VINCI/VLTI instrument was obtained. And the authors derived internal structure models corresponding to ages between 200 and 250 +/- 12 Myr, based on the hypothesis on the mass of the star, the overshoot and the metallicity.
Journal ArticleDOI
L'-Band Interferometric Observations of Evolved Stars
G. Chagnon,Bertrand Mennesson,Guy Perrin,V. Coudé du Foresto,P. Salomé,P. Bordé,Marc G. Lacasse,Wesley A. Traub +7 more
TL;DR: In this paper, visibility measurements and best fits for all 18 stars in the sample were derived and strong departures from UD models in some peculiar cases were also detected in some unusual cases.
