Metallicity gradients in dwarf elliptical galaxies
We discuss the relations between the metallicity gradients and the other characteristics of a set of dwarf elliptical galaxies in different environments. We...
Metallicity of the Monoceros Stream from A/F-type Stars
We have obtained metallicity estimates for a sample of A/F-type stars that appear to be members of the recently discovered Monoceros Stream. This sample of...
Meteor Outbursts - Amateur Visual Observations are more valuable than ever
1998 was one of the most exciting years ever for meteor observers. No less than three showers (the Pons-Winneckids, the Giacobinids and the Leonids) gave...
Meteorite, a rock from space: A planetarium adventure for children
At the Museum of the Science and the Cosmos (MCC, La Laguna, Tenerife) there is a small planetarium. All the different planetarium shows are carried out...
Method for the determination of density and phase functions of interplanetary dust
A method of determination of the scattered light intensity by a unit volume of interplanetary space is presented. From ground-based zodiacal light measurements...
