Spectroscopic analysis of accretion/ejection signatures in the Herbig Ae/Be stars

Time series analysis of two high-resolution UVES / ESO spectra stars Herbig Ae/Be members of the young star cluster NGC 2264 with indications of sufficient circumstellar material so that the addition and ejection processes. Determination of stellar parameters with synthetic spectral adjustment, and study the variability of the emission lines and classified the circumstellar lines, such as Halpha, Hbeta, according to its morphologies. Halpha medium profile model, using a hybrid MHD model that includes a stellar magnetosphere and a disk wind
