To interpret these observations, we run a cosmological simulation in a 30h −1 cMpc/size volume down to z ≈ 4. The recent discovery of high redshift dusty galaxies implies a rapid dust enrichment of their interstellar medium (ISM). in the Fornax dwarf galaxy and elliptical galaxies in the context of Based on the present new results, we also discuss the origins of Studies on for the LMC have been recently accumulated for a detailedĬomparison. The Large Magellanic Cloud (LMC), because a growing number of observational We compare these results with the observed elemental features of stars in Result of this, can be systematically higher in the models with dust Without dust wind owing to the lower level of dust depletion for Mg. , on the other hand, can not be so different between the models with and Systematically lower in the models with dust wind. Models with and without dust wind in the sense that can be The time evolution of is significantly different between Model parameters for dust wind in this study. Particularly focus on the time evolution of and its dependence on Interstellar medium and the total luminosity of the galaxy in the new model.
(e.g., Fe, Mg, and Ca) through radiation-driven dust wind in a galaxy isĪssumed to depend both on the dust depletion level of the element in Stars influences the chemical evolution of galaxies by using a new one-zoneĬhemical evolution models with dust wind. We discuss how the removal of interstellar dust by radiation pressure of
