Statistical tests with multi-wavelength Kernel-phase analysis for the detection and characterization of planetary companions
Mamadou N'Diaye, David Mary, Frantz Martinache +4
Kernel phase is a method to interpret stellar point source images by considering their formation as the analytical result of an interferometric process. Using Fourier formalism, th…
Orbital and dynamical analysis of the system around HR 8799. New astrometric epochs from VLT/SPHERE and LBT/LUCI
A. Zurlo, K. Gozdziewski, C. Lazzoni D. Mesa +44
HR\,8799 is a young planetary system composed of 4 planets and a double debris belt. Being the first multi-planetary system discovered with the direct imaging technique, it has bee…
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…
Resolving the planet-hosting inner regions of the LkCa 15 disk
C. Thalmann, M. Janson, A. Garufi +28
LkCa 15 hosts a pre-transitional disk as well as at least one accreting protoplanet orbiting in its gap. Previous disk observations have focused mainly on the outer disk, which is…
Transiting exoplanets and magnetic spots characterized with optical interferometry
R. Ligi, D. Mourard, A. -M. Lagrange +2
Stellar activity causes difficulties in the characterization of transiting exoplanets. Studies have been performed to quantify its impact on infrared interferometry, but not in the…
Planet transit and stellar granulation detection with interferometry
Andrea Chiavassa, Roxanne Ligi, Zazralt Magic +3
Aims. We used realistic three-dimensional (3D) radiative hydrodynamical (RHD) simulations from the Stagger-grid and synthetic images computed with the radiative transfer code Optim…
