... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... The stars of the middle main sequence have relatively quiescent outer layers, and unusual chemical abundance patterns may develop in their atmospheres. ... At present, little is known about the time evolution of these anomalous abundances, nor about the role that diffusion may play in maintaining them, during the main sequence lifetime of such a star. ...

... Programme . ... Abstract: Planetary nebulae constitute a unique source of light element abundances for individual stars in a distant stellar population. Multi-slit spectra of 50 planetary nebulae (PN) in NGC 5128 have been observed with the ESO VLT and FORS1 spectrometer. The planetary nebulae were observed in three fields covering a range of galactic radii from 2 to 19 kpc. The emission line spectra have been analysed for light element abundances (He, O, N, Ne, S, Ar). ...
