Dynamical and chemical evolution in gas-rich dwarf galaxies
We study the effect of a single, instantaneous starburst on the dynamical and chemical evolution of a gas-rich dwarf galaxy, whose potential well is dominated by a dark matter halo. We follow the dynamical and chemical evolution of the ISM by means of an improved 2-D hydrodynamical code coupled with detailed chemical yields originating from type II SNe, type Ia SNe and single low and intermedia...

متن کاملThe Chemical Evolution of Gas-rich Dwarf Galaxies
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 region evolution and develop a numerical model of chemical evolution based on a double-bursting mode of star formation (with an interval of the order of 3×10 7 years between bursts of a pair) which has been designed to a...
متن کاملChemical and dynamical evolution in gas-rich dwarf galaxies
We study the effect of a single, instantaneous starburst in a gas-rich dwarf galaxy on the dynamical and chemical evolution of its interstellar medium. We consider the energetic input and the chemical yields originating from SNeII, SNeIa and intermediate-mass stars. We find that a galaxy resembling IZw18 develops a galactic wind carrying out mostly the metal-rich gas. The various metals are los...
متن کاملGas Dynamics and Inflow in gas - rich Galaxy Mergers
We performed N-body/SPH simulations of merging gas-rich disk galaxies with mass ratios of 1:1 and 3:1. A stellar disk and bulge component and a dark halo was realized with collisionless particles, the gas was represented by SPH particles. Since we did not include star formation we focused on the gas dynamics and its influence on the structure of merger remnants. We find that equal-mass mergers ...
