Spatially resolved spectroscopy of WR ring nebulae. III - New results and chemical properties of the sampleThe paper presents detailed high-spatial-resolution spectroscopy of seven WR ring nebulae, observed at several telescopes in both hemispheres. These are Anon (MR 26), Anon (MR 100), G 2.4 + 1.4, L 69.8 + 1.74, NGC 3199, RCW 104, and S 308. Using line diagnostic diagrams, it is found that photoionization is the main excitation source in the sampleEsteban, C. et al.

Multiband analysis of the surface brightness distributions of SB and SC spirals CCD images. I - ObservationsResults are presented of an imaging study of eight Sb-Sc spirals, based on CCD observations in the B, V, R, I, and Z photometric filters. Presented are grey scale images, both in individual bands and in color indices, isophote maps, the parameters of the best fits to the isophotes (ellipticity and position angle as functions of deprojected radius)Prieto, M. et al.

Lithium abundances in classical and weak T Tauri starsA study on the lithium abundance in 36 T Tauri stars (mass range 0.4-2.25 solar masses), partly based on high-dispersion spectra taken with the Isaac Newton Telescope, is presented. A study of non-LTE effects in the formation of the lithium double in T Tauri stars and derived corrections to the abundances in the LTE in the range 1.0-4.0 log N(Li)Magazzu, Antonio et al.
