The heaviest iron-peak element, Zn has been used as an important tracer of cosmic chemical evolution. Spectroscopic observations of the metal-poor stars in Local Group galaxies show that an increasing trend of [Zn/Fe] ratios toward lower metallicity. However, enrichment of Zn in galaxies is not well understood due to the poor knowledge of astrophysical sites of Zn as well as metal mixing in galaxies. Here we show possible explanations for the observed trend by taking into account electron… Expand

This chapter aims to clarify the role of supernovae (core-collapse supernovae, electron-capture supernovae, hypernovae, and type Ia supernovae) to the chemical evolution of galaxies. We focus on theExpand
Enrichment of Heavy Elements in Chemo-Dynamical Simulations of Dwarf Galaxies
Abstract Abundances of heavy elements in dwarf galaxies reflect their early evolutionary histories. Recent astronomical observations have shown that there are star-to-star scatters in the abundancesExpand
Enrichment of Strontium in Dwarf Galaxies
Light trans-iron elements such as Sr serve as the key to understanding the astrophysical sites of heavy elements. Spectroscopic studies of metal-poor stars have revealed large star-to-star scattersExpand
Efficiency of Metal Mixing in Dwarf Galaxies
Stars inherit the elemental abundances of ejecta from nucleosynthetic events mixed in the interstellar medium. The abundances of heavy elements in stars contain information about the metal mixing inExpand

A New Test of Copper and Zinc Abundances in Late-Type Stars Using Ultraviolet Cu II and Zn II Lines
We present new abundances derived from Cu I, Cu II, Zn I, and Zn II lines in six warm (5766 < Teff < 6427 K), metal-poor (-2.50 < [Fe/H] < -0.95) dwarf and subgiant (3.64 < log g < 4.44) stars. TheseExpand
Primordial to extremely metal-poor AGB and Super-AGB stars: White dwarf or supernova progenitors?
Abstract Getting a better understanding of the evolution and nucleosynthetic yields of the most metal-poor stars (Z ≲ 10−5) is critical because they are part of the big picture of the history of theExpand
Evidence for an Aspherical Population III Supernova Explosion Inferred from the Hyper-metal-poor Star HE 1327–2326
We present observational evidence that an aspherical supernova explosion could have occurred in the First stars in the early universe. Our results are based on the First determination of a ZnExpand
From Actinides to Zinc: Using the Full Abundance Pattern of the Brightest Star in Reticulum II to Distinguish between Different
The ultra-faint dwarf galaxy Reticulum II was enriched by a rare and prolific r-process event, such as a neutron star merger. To investigate the nature of this event, we present high-resolutionExpand
