We present a color magnitude diagram (CMD) in the V and I bands reaching 4 magnitudes below the turn off (TO) and intermediate resolution spectra for 4 giant branch (GB) stars. The spectra allowed us to determine the cluster metallicity and radial velocity for the cluster Pal 1. The metallicity has been determined using the CaII triplet and other

To study some physical properties of comets of the Jupiter Family, we have compiled a new catalog of nuclear magnitudes. As a source for the catalog we have used Kamel's (1992) compilation of data from many different sources, adding measurements of nuclear magnitudes for the period: mid 1990 - mid 1996, taken from the IAU Circulars, MPCs, ICQs and

The studies of the emergence of magnetic flux across the convection zone show how the individual magnetic tubes rise toward the surface at the same time remaining anchored at the interface between the convection zone and the radiative interior. A number of recent numerical simulations, in particular, reproduce several observed features of the
