PublicaciónA Minor-Merger Origin for Inner Disks and Rings in Early-Type Galaxies
Nuclear disks and rings are frequent galaxy substructures, for a wide range of morphological types [from S0 to Sc, see e.g., 1, 2]. We have investigated the...
PublicaciónA photometric study of the double ring structure of NGC 4736
Photometric results for the galaxy NGC 4736 are presented, including IR and visible profiles. After correction for the extinction within the galaxy based on...
PublicaciónAbundance analysis of giant H II regions in M51
Spectrophotometric observations in the optical and near-infrared of six giant H II regions in the high metallicity spiral galaxy M51 are presented. Five of the...
PublicaciónAbundance analysis of giant H II regions in nearby spirals.
Spectrophotometric data of giant H II regions covering the spectral range from λ3600 to 9700 Å in the spiral galaxies M101 and M51 have been analyzed in order...
PublicaciónAbundance Gradients in M33: the Use of Planetary Nebulae
We present our observations of several planetary nebulae in the central zones of the spiral galaxy M33. We combine the abundances we derived for our objects...
PublicaciónAn improved evolutionary model for stellar population applied to NGC 2903
The revised physical assumptions incorporated into a previously published evolutionary model for stellar population synthesis in galaxies (Casuso et al., 1989)...
