BRICS Southern Observatory (BRICS-SO) Project: Invitation to African countries to invest in Chile
Massinissa Hadjara, Amokrane Berdja, Swagat R. Das +6
Recently, the BRICS countries created a promising astronomy consortium (https://www.bricsastronomy.org/), which was joined last year by some emerging countries, including two Afric…
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…
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…
A binary engine fuelling HD87643' s complex circumstellar environment, using AMBER/VLTI
Florentin Millour, Olivier Chesneau, Marcelo Borges Fernandes +19
Context. The star HD 87643, exhibiting the "B[e] phenomenon", has one of the most extreme infrared excesses for this object class. It harbours a large amount of both hot and cold d…
The gamma Dor CoRoT target HD49434. I-Results from the ground-based campaign
K. Uytterhoeven, P. Mathias, E. Poretti +22
Context: We present the results of an extensive ground-based photometric and spectroscopic campaign on the gamma Dor CoRoT target HD49434. This campaign was preparatory to the CoRo…
