Keck Observatory, USA, MMT Observatory, Tucson, USA, Universitäts-Sternwarte, Goettingen, Germany, National Optical Astronomy Observatories, Tucson, USA, University of Virginia, Charlottes | | Abstract: | The results of the N/O abundance determination in a sample of low-metallicity blue compact dwarf (BCD) galaxies based on new spectroscopic observations with large telescopes (Keck, VLT, MMT, 4m KPNO) are presented. We show that the N/O abundance ratio is constant at lowest metallicities < Zsun/20, confirming previous findings and strongly supporting the origin of nitrogen as a primary element. | | Source: | arXiv, astro-ph/0109519 | | Services: | Forum | Review | PDF | Favorites | |
