Context. HD 181231 and 175869 are two late rapidly rotating Be stars, which have been observed using high-precision photometry with the CoRoT satellite during about five consecutive months 27 days, respectively. An analysis of their light curves, by Neiner collaborators Gutiérrez-Soto respectively, showed that several independent pulsation g-modes present in these stars. Fundamental parameters also determined authors spectroscopy.
HD49330 is a Be star that underwent an outburst during its five-month observation with the CoRoT satellite. An analysis of light curve revealed several independent p and g pulsation modes, in addition to showing amplitude modes directly correlated outburst. We modelled results obtained CoRoT. flattening structure due rapid rotation two ways: Chandrasekhar-Milne's expansion 2D computed ROTORC. then kappa-driven pulsations. also adapted formalism excitation stochastically excited...
