En la primera parte de esta charla comentaré un poco, y de forma muy general, sobre la actividad magnética en las estrellas y, en particular, sobre una de sus manifestaciones, como son las manchas, tanto en el Sol como en otras estrellas.

Como la descripción del estado de polarización de la luz policromática precisa de la especificación de 4 parámetros (en realidad, tres parámetros libres más una condición de ligadura), el formalismo más empleado es el de los (4) parámetros de Stokes.

I will present a brief review of the main HI properties of isolated, normal spiral galaxies and of the phenomena which characterize and dominate their internal metabolism. In particular, I will present and discuss new results on the HI halos and on the HI disk-halo connection.

I will talk about some comparative aspects of the evolution of Mars and Earth. Today, the surface of Mars appears dry and lifeless, and the atmospheric composition is defined by chemical processes.
We have studied the gas kinematics in the inner regions of a sample of 23 disk galaxies obtained from long-slit spectra along their major axis. We discuss the variety of the shapes of the emission lines in the position-velocity

Do the spiral galaxies still evolve? Abundance gradient is a powerful tracer of the galactic evolution. It the past, it as been demonstrated that large scale flow of gaz induce by bar can flatten the gradient.

String theory, which is supposed to be the fundamental theory of quantum gravity, has now mutated into membrane theory (brane theory), and given rise to some peculiar cosmological models called "brane cosmologies".

Remarkable correlation between the Ha emission line and the radio behaviour of LSI+61 303 (GT 0236+610) over its 4 yr modulation is discovered. The radio outburst peak is shifted with 400 d with respect to the Ha equivalent width.
