We analyse interferometric data obtained for Regulus with AMBER (Astronomical Multi- BEam combineR) at high spectral resolution ($\lambda/\delta\lambda \approx 12000$) across the Br$\gamma$ spectral line. The study of the photocentre displacement all

Astronomical optical interferometry, II: Astrophysical results

Autor: S. Jankov

Publikováno v: Serbian Astronomical Journal, Vol 2011, Iss 183, Pp 1-35 (2011)

Optical interferometry is entering a new age with several ground- based long-baseline observatories now making observations of unprecedented spatial resolution. Based on a great leap forward in the quality and quantity of interferometric data, the as

Stellar activity and magnetism studied by optical interferometry

Autor: Oleg Kochukhov, Martin Kilbinger, Thierry Lanz, S. Jankov, C. Stehlé, T. Boudoyen, J.-B. Le Bouquin, K. Rousselet-Perraut

Publikováno v: Astronomy & Astrophysics. 422:193-203

By means of numerical simulations, we investigate the ability of optical interferometry, via the fringe phase observ- able, to address stellar activity and magnetism. To derive abundance maps and stellar rotation axes, we use color differential inter

Ori is a B2IIIe star for which rotational modulation and non-radial pulsations (NRP) have been recently investi- gated from two independent observational campaigns in 1998 and 1999. Putting the data of these 2 campaigns together, and adding data obta

Publikováno v: Astronomy & Astrophysics. 393:345-357

Optical long baseline interferometry is a powerful tool to study detailed stellar structures. In particular, rapid rotation induces interferometric signatures requiring a detailed modelling for correctly interpreting high angular resolution data. In
