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…
Potential and sky coverage for off-axis fringe tracking in optical long baseline interferometry
Abdelkarim Boskri, Romain G. Petrov, Thami El Halkouj +6
The spectacular results provided by the second-generation VLTI instruments GRAVITY and MATISSE on active galactic nuclei (AGN) trigger and justify a strong increase in the sensitiv…
A CO-multilayer outer atmosphere for eight evolved stars revealed with VLTI/AMBER
M. Hadjara, P. Cruzalèbes, C. Nitschelm +3
We determine the physical parameters of the outer atmosphere of a sample of eight evolved stars, including the red supergiant α Scorpii, the red giant branch stars α Bootis and γ C…
Spatially resolving the atmosphere of the non-Mira-type AGB star SW Vir in near-infrared molecular and atomic lines with VLTI/AMBER
K. Ohnaka, M. Hadjara, M. Y. L. Maluenda Berna
We present a near-infrared spectro-interferometric observation of the non-Mira-type, semiregular asymptotic giant branch star SW Vir. Our aim is to probe the physical properties of…
Differential interferometry of the rapid rotator Regulus
M. Hadjara, R. G. Petrov, S. Jankov +3
We analyse interferometric data obtained for Regulus with AMBER (Astronomical Multi- BEam combineR) at high spectral resolution () across the Br spectral line…
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…
