Numerical models of chemical evolution have been computed for a sample of 40 dwarf
irregular galaxies by assuming bursts of star formation and taking galactic winds into …

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 …

Within the framework of the closed box model of chemical evolution of galaxies the evolution
of nitrogen and oxygen abundances in dwarf irregular galaxies is considered. We show that …

We present one-zone chemical evolution models for two dwarf starburst galaxies, NGC 1705
and NGC 1569. Though especially designed for the inner∼ 1 kpc region, where numerous …

In an effort to understand the evolution of N, O and He abundances in gas-rich dwarf
galaxies, we investigate the dispersion and mixing of supernova ejecta in relation to H ii …

We use data for faint (MB>− 14.5) dwarf irregular galaxies drawn from the Faint Irregular
Galaxy GMRT Survey to study the correlation between the surface densities of atomic gas …

In order to recognize environmental effects on the evolution of dwarf galaxies in clusters of
galaxies, it is first necessary to quantify the properties of objects that have evolved in relative …

On the Evolution of Helium Nitrogen and Oxygen Abundances in Dwarf Irregular Gal ADS
Classic is now deprecated. It will be completely retired in October 2019. This page will …

Supernova and multiple supernova events regulate several structural properties of dwarf
galaxies. In particular, they govern the metal enrichment and the energy budget of the ISM; …

Aims. We study the oxygen and nitrogen abundances in the interstellar medium of high-
redshift galaxies. Methods. We use high resolution and high signal-to-noise ratio spectra of …
