Oxygen and Nitrogen in Isolated Dwarf Irregular Galaxies
We present long slit optical spectroscopy of 67 H II regions in 21 dwarf irregular galaxies to investigate the enrichment of oxygen, nitrogen, neon, sulfur, and argon in low mass galaxies. Oxygen abundances are obtained via direct detection of the temperature sensitive emission lines for 25 H II regions; for the remainder of the sample, oxygen abundances are estimated from strong line calibrati...
متن کاملThe Oxygen Abundance Calibrations and N/o Abundance Ratios of ∼ 40,000 Sdss Star-forming Galaxies
Using a large sample of 38,478 star-forming galaxies selected from the Second Data Release of the Sloan Digital Sky Survey database (SDSS-DR2), we derive analytical calibrations for oxygen abundances from several metallicity-sensitive emission-line ratios: [N ii]/Hα, [O iii]/[N ii], [N ii]/[O ii], [N ii]/[S ii], [S ii]/Hα, and [O iii]/Hβ. This consistent set of strong-line oxygen abundance cali...
متن کاملStellar Structure of Irregular Galaxies . I . Face - on Galaxies
Stellar photometry of nearby irregular galaxies of the Local Group is used to identify and study the young and old stellar populations of these galaxies. An analysis of the spatial distributions of stars of different ages in face-on galaxies shows that the young stellar populations in irregular galaxies are concentrated toward the center, and form local inhomogeneities in star-forming regions, ...
متن کاملStellar Structure of Irregular Galaxies . Edge - On Galaxies
Stellar photometry obtained using the Hubble Space Telescope is used to study the distributions of the number densities of stars of various ages in 12 irregular and dwarf spiral galaxies viewed edge-on. Two subsystems can be distinguished in all the galaxies: a thin disk comprised of young stars and a thick disk containing a large fraction of the old stars (primarily red giants) in the system. ...
متن کاملDwarf Irregular Galaxies ? Liese
New observations of 16 dwarf elliptical galaxies in the Virgo Cluster indicate that at least seven dEs have significant velocity gradients along their optical major axis, with typical rotation amplitudes of 20-30 km s. Of the remaining nine galaxies in this sample, 6 have velocity gradients less than 20 km skpc while the other 3 observations had too low of a signal–to–noise ratio to determine a...
