The characteristics of the IR emission features in the spectra of Herbig Ae stars: Evidence for chemical evolution

Autor: Boersma, C., Bouwman, J., Lahuis, F., van Kerckhoven, C., Tielens, A. G. G. M., Waters, L. B. F. M., Henning, Th.

Herbig Ae/Be stars are a class of young pre-main sequence stellar objects of intermediate mass and are known to have varying amounts of natal cloud material still present in their direct vicinity. We characterise the IR emission bands, due to fluores

Here, we present 6-9 um spectra of a sample of RNe, HII regions, YSOs, evolved stars and galaxies that show strong unidentified infrared bands, obtained with the ISO-SWS. The IR emission features show pronounced variations. 1) The 6.2 um feature shif

ISO has shown that the mid-IR spectra of almost all sources are dominated by narrow emission features collectively known as the UIR bands. These bands are carried by a family of polycyclic aromatic hydrocarbon molecules containing about 60 C-atoms. O
