We compare the rate of kinetic energy injected by stellar winds into the extragalactic H II region NGC 2363 to the luminosity needed to feed the observed temperature fluctuations. The kinetic luminosity associated to the winds is estimated by means of two different evolutionary synthesis codes, one of which takes into account the statistical

We present an atlas of position-velocity (PV) diagrams of ionized gas in the inner regions of 23 disk galaxies. The gas kinematics have been obtained from ground-based long-slit spectra along the major axis. We discuss the variety of shapes of the emission lines in the PV diagrams that we find for the sample galaxies. To discuss the different

We present high signal-to-noise Keck spectra for 10 globular clusters associated with the giant Fornax elliptical galaxy NGC 1399 and compare measured line indices with current stellar population models. Our data convincingly demonstrate, for the first time, that at least some of the clusters in a giant elliptical galaxy have supersolar abundance

We briefly communicate about 21st run of the Whole Earth Telescope (WET) in April 2001, where the eclipsing short period binary sdB system PG 1336-018 was the primary target.
