| contents | The Interacting Wolf-Rayet Galaxy Haro 15 César Esteban Angel R. López Sánchez Física, Astronomía y Matemáticas Rayet stars : Wolf Galaxies : Kine Matics and Dynamics Galaxies : Abundances Only less than 150 Wolf-Rayet galaxies are actually known. Many of them are dwarf or irregular galaxies, and some show close companion objects. Peculiar morphological features, like mergers or tidal tails connecting small stellar aggregates, are found in many cases. Therefore, we think that interaction could be an important mechanism that triggers star formation in Wolf-Rayet galaxies, interestingly in dwarf ones. We have used deep optical and near-infrared CCD imagery and intermediate resolution optical spectroscopy to analyse some Wolf-Rayet galaxies and surrounding objects in order to study their inter-relation. Some of the conclusions about the morphology, kinematics, colors and the chemical composition of the ionized gas of Haro 15 are shown. We have also analysed the ages of the observed bursts making use of spectral synthesis models. 2003 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57101812 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.18 |
