Chemical evolution of the galaxy
AIP Conference Proceedings, 1995The article presents data on and discussion of various issues related to element abundance trends in our Galaxy as a function of metallicity [Fe/H]: halo star abundances, evolution of the Galactic supernova rates, the age‐metallicity relationship for disk stars, and halo and disk star formation history and nycleosynthesis timescales. (AIP)

The Chemical Evolution of the Galaxy: The Two‐Infall Model [PDF]
Astrophysical Journal, 1997 In this paper we present a new chemical evolution model for the Galaxy which assumes two main infall episodes for the formation of halo-thick disk and thin disk, respectively. We do not try to take into account explicitly the evolution of the halo but we implicitly assume that the timescale for the formation of the halo was of the same order as the ...

Monthly Notices of the Royal Astronomical Society, 2015 We present detailed chemical element abundance ratios of 17 elements with eight ≤ Z ≤ 60 in three metal-poor stars in the Ursa Minor dwarf spheroidal galaxy, which we combine with extant data from the literature to assess the predictions of a novel suite

Chemical evolution during gas-rich galaxy interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We perform and analyse a set of galaxy interactions performed by using a self-consistent chemo-hydrodynamical model which includes star formation, supernova (SN) feedback and chemical evolution.

The Chemical Evolution of Galaxies
Progress in Particle and Nuclear Physics, 1986After a brief introduction into the evolution of spiral galaxies, the observational evidence for temporal and spatial abundance variations across the galactic disk is discussed. The theoretical framework of chemical evolution models is summarised, followed by a critical discussion of available constraints. Solutions applying to the special cases of the

The Chemical Evolution of Dwarf Galaxies
Astrophysics and Space Science, 2001Various observations of dwarf starburst galaxies have revealed homogeneous abundance within the ionized region suggesting that the measured metallicities do not result from the metals ejected during the current burst (because they should not have time to mix homogeneously at such large scale) but from previous star formation episodes.

Chemical Evidence for Evolution of Galaxies
Astrophysics and Space Science, 2001I have compiled the very best data published on abundance gradients. From this sample of 29 galaxies, some information can be gained on the mecanism of morphological evolution in disk galaxies. From this sample, I find that early-type galaxies show an identical trend in the behavior of extrapolated central abundance versus morphological type to that ...

The chemical evolution of galaxies
Journal of Physics G: Nuclear and Particle Physics, 1993The chemical evolution of galaxies is discussed starting with the simple box model. It is shown that this model with the additional assumption of metal-rich outflow provides a first useful insight into the chemical evolution of different stellar populations.

The chemical evolution of galaxies
Vistas in Astronomy, 1975Abstract Emphasis is placed on the simplest models of the chemical evolution of galaxies, and the role played by the concentration of the interstellar gas to gravitational stable regions is taken into account. Although Schmidt's simple model is improved when concentration is allowed for, it still predicts too wide a spread of metal abundances for ...
