Optical and infrared observations of the H II region S201Optical spectroscopy, H-alpha interferometry, and near-IR mapping and photometry of the bipolar H II region S201 are reported. The observations are used to place constraints upon the energetics of the H II region as well as to provide a clearer understanding of the IR structure. The exciting star is coincident with a central bar of obscuringMampaso, A. et al.

Numerical determination of the modulation transfer function from observations of granulation outside the disk centre.A spectral ratio, similar to that of von der Lühe (1984), is proposed to derive information on the degradation of the mean granular power spectrum at a position outside the disk centre. It has the advantage that the modulation transfer function is obtained directly from the data, without making any assumption on turbulence theory to describe theHidalgo, I. R. et al.

V-R diagram for spiral galaxies - New insights into the Hubble sequenceThe present examination of the relation between the global parameters of spiral galaxies and their morphological type represents rotational velocity V at 25 mag/sq arcsec radius against this radius R for a 56-galaxy sample. Isolines of total mass, angular momentum, and mean surface density, plotted above the V-R diagram for isolated galaxies withPrieto, M. et al.
