The nature of arms in spiral galaxies. I - Azimuthal colour profiles of NGC 7479 and NGC 1832A set of parameters to characterize azimuthal profiles of galaxies is proposed and applied to the spiral structure of the galaxies NGC 1832 and NGC 7479 observed in the B and I passbands. Interpretations of the observations in terms of the two most widely discussed theories of star formation, the spiral density wave theory and that of selfBeckman, J. E. et al.

Spectral and radial velocity studies of 5 northern central stars of planetary nebulaeSpectrograms of five bright northern central stars of planetary nebulae (CSPN) are compiled in order to provide spectral descriptions of these stars, with particular attention given to the central stars of NGC 6543 and NGC 6572 (the best examples of the Of WR spectral class) and a comparison of these to less extreme Of CSPN. Results present clearMendez, R. H. et al.

Phase differences between luminosity and velocity measurements of the acoustic modesWith two photometric stations (Tenerife and Baja California) the luminosity p-mode spectrum at different wavelengths has been identified. After a coherence analysis between data from both stations to verify the solar origin of the peaks identified in luminosity, a comparative study with simultaneous velocity measurements (obtained at Tenerife only)Jimenez, A. et al.
