Presentation 1 : Oral
Modelization of the two giant HII regions NGC 588 and NGC 595
L. Jamet, G. Stasinska, E. Perez, R. Gonalez-Delgado, J. Vilchez
I will present the results of the study of these two objects, based on
observations made by E. Perez, R Gonzalez-Delgado & J Vilchez (IAA, Granada). These long-slit, high signal-to-noise spectra, completed by archived data from HST, IUE and ISO and ground-based images, will alow to achieve an accurate modelization of the nebulae. Their ionising sources are modelled with Starburst99; then, Stasinska's code PHOTO is to be used to understand the ionization conditions of the two nebulae.
