Abstract
  • The VLTI (Very Large Telescope Interferometer) makes available milli-arcsecond-scale observations in the infrared. It offers new possibilities for constraining stellar structures such as polar jets, equatorial disks and rotationally-flattened photospheres of Be stars. Such constraints allows us to better estimate the stellar fundamental parameters and refine the mechanisms such as mass loss, pulsation and magnetism that govern the variability and evolution of these stars. In this paper we present a chromatic semi-analytical model of fast rotators, which allows us to study the dynamics and the interaction between the photosphere and the wind of fast rotating stars of O, B, A and F spectral types. Our simple analytical model addresses the oblateness, inclination and position angle of the rotation axis of the star. It produces iso-velocity maps and intensity maps. It includes line profiles, limb-darkening and the von Zeipel effect and the non-radial pulsations. SCIROCCO+: Simulation Code of Interferometric-observations for ROtators and Cir Cumstellar Objects including Non-Radial Pulsations, includes all the parameters cited above in order to be fast, powerful and light simulation tool in high angular resolution of rotating objects.
