We present abundances of neon, nitrogen and oxygen of some nearby dwarf irregular
galaxies. The elemental abundances are retrieved from long-slit spectroscopy of H ii regions …

Optical spectra of H ii regions of two dwarf irregular galaxies are presented. The objects are
IC 4662 and ESO 245-G05. Chemical abundances were derived in all the H ii regions where …

The results of optical spectroscopy of regions in a sample of southern dwarf irregulars
consisting of five dwarf galaxies in the Centaurus A group, four dwarfs in the Sculptor group …

Deep groundbased spectra of Hubble V and Hubble X, the two largest and brightest H ii
regions in the Local Group dwarf galaxy, NGC 6822, are presented. The extinction …

The spectral characteristics throughout the dwarf irregular galaxy DDO 53 are studied. The
results are very similar to those for other irregular galaxies: high excitation and low values of …

Chemical abundances in three M supergiants in the Local Group dwarf irregular galaxy IC
1613 have been determined using high-resolution spectra obtained with the UVES …

We have derived nebular abundances for 10 dwarf galaxies belonging to the M81 Group,
including several galaxies which do not have abundances previously reported in the …

We present new results from optical spectroscopy of the brightest Hii region in the dwarf
irregular galaxy in Sagittarius (SagDIG). From high signal-to-noise spectra, reddening …

Optical Colors and the Metallicities of Gas-Rich Quiescent Dwarf Galaxies ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

The low-luminosity dwarf irregular galaxies are considered. The oxygen abundances in H ii
regions of dwarf irregular galaxies were recalculated from published spectra through the …
