Chemo-dynamical simulations of galaxies
We simulate the formation and evolution of galaxies with a self-consistent 3D hydrodynamical model including star formation, supernova feedback, and chemical enrichment. Hypernova feedback plays an essential role not only in solving the [Zn/Fe] problem, but also reproducing the cosmic star formation rate history and the mass-metallicity relations. In a MilkyWay type galaxy, kinematics and chemi...
متن کاملCHEMO – DYNAMICAL EVOLUTION OF DISK GALAXIES, SMOOTHED PARTICLES HYDRODYNAMICS APPROACH Chemo – Dynamical SPH code
A new Chemo – Dynamical Smoothed Particle Hydrodynamic (CD – SPH) code is presented. The disk galaxy is described as a multi – fragmented gas and star system, embedded into the cold dark matter halo. The star formation (SF) process, SNII, SNIa and PN events as well as chemical enrichment of gas have been considered within the framework of standard SPH model. Using this model we try to describe ...

متن کاملChemo-dynamical Evolution of the ISM in Galaxies
Chemo-dynamical models have been introduced in the late eighties and are a generally accepted tool for understanding galaxy evolution. They have been successfully applied to one-dimensional problems, e.g. the evolution of nonrotating galaxies, and two-dimensional problems, e.g. the evolution of disk galaxies. Recently, also three-dimensional chemo-dynamical models have become available. In thes...
متن کاملA Numerical Study of the Chemo-Dynamical Evolution of Elliptical Galaxies
We investigate the chemo-dynamical evolution of elliptical galaxies, to understand the origin of the mass-dependence of photometric properties such as the colour-magnitude relation (CMR). Our threedimensional TREE N-body/SPH numerical simulation takes into account both Type II and Type Ia supernovae and follows the evolution of the abundances of several chemical elements. We derive the photomet...
