Abundance analysis of three new extremely metal-poor stars, including one CEMP-s star
P. François, T. Suda, S. Wanajo +5
We report a detailed abundance analysis of three extremely metal-poor (EMP) stars thanks to spectra obtained with the high-dispersion spectrograph (HDS) at the Subaru telescope. Th…
Potassium abundances in extremely metal poor stars: Implications for nucleosynthesis in the final stages of massive star evolution
M. N. Ishigaki, N. Tominaga, W. Aoki +5
We present a potassium (K) abundance analysis in extremely metal-poor (EMP) stars based on high-resolution () spectra obtained with the High Dispersion Spectrograph on…
Detailed Chemical Abundance Analysis of Metal-Poor Turn-Off Stars: One with [Fe/H] < -4 and Three with [Fe/H] < -3
Takuma Suda, Patrick Francois, Shinya Wanajo +3
We present the analysis of four new extremely metal poor turn-off stars thanks to high-resolution spectra obtained with the Subaru/HDS spectrograph. We determined the abundances an…
Detailed abundances in a sample of very metal poor stars
P. François, S. Wanajo, E. Caffau +6
Unevolved metal poor stars are the witness of the early evolution of the Galaxy. The determination of their detailed chemical composition is an important tool to understand the che…
A New Model for Electron-Capture Supernovae in Galactic Chemical Evolution
S. Jones, B. Côté, F. K. Roepke +1
We examine the contribution of electron-capture supernovae (ECSNe), low-mass SNe from collapsing Fe cores (FeCCSNe), and rotating massive stars to the chemical composition of the G…
Simulations of Electron Capture and Low-Mass Iron Core Supernovae
B. Müller, S. Wanajo, H. -Th. Janka +3
The evolutionary pathways of core-collapse supernova progenitors at the low-mass end of the spectrum are beset with major uncertainties. In recent years, a variety of evolutionary…
