The binary system of the spinning-top Be star Achernar

P. Kervella, S. Borgniet, A. Domiciano de Souza +16

Achernar, the closest and brightest classical Be star, presents rotational flattening, gravity darkening, occasional emission lines due to a gaseous disk, and an extended polar win…

Application limit of the photocentre displacement to fundamental stellar parameters of fast rotators -- Illustration on the edge-on fast rotator Regulus

M. Hadjara, R. G. Petrov, S. Jankov +16

Differential Interferometry allows to obtain the differential visibility and phase, in addition to the spectrum. The differential phase contains important information about the str…

Refined fundamental parameters of Canopus from combined near-IR interferometry and spectral energy distribution

A. Domiciano de Souza, J. Zorec, F. Millour +3

Canopus, the brightest and closest yellow supergiant to our Solar System, offers a unique laboratory for understanding the physics of evolved massive stars. The accurate and precis…

Regulus observed with VLTI/AMBER

S. Jankov, M. Hadjara, R. G. Petrov +3

The rapidly rotating primary component of Regulus A system has been observed, for the first time, using the technique of differential interferometry at high spectral resolution. Th…

VEGA/CHARA interferometric observations of Cepheids. I. A resolved structure around the prototype classical Cepheid delta Cep in the visible spectral range

N. Nardetto, A. Mérand, D. Mourard +23

The B-W method is used to determine the distance of Cepheids and consists in combining the angular size variations of the star, as derived from infrared surface-brightness relation…
