The impact of supernova feedback on metallicity-gradient evolution in cosmological simulations
Dyna Ibrahim, Chiaki Kobayashi
Tracing the cosmic path of galaxies requires an understanding of their chemical enrichment and merging histories. One of the most important constraints is the internal structure of…
Constraining Nucleosynthesis in Two CEMP Progenitors Using Fluorine
A. Mura-Guzmán, D. Yong, C. Abate +6
We present new fluorine abundance estimations in two carbon enhanced metal-poor (CEMP) stars, HE 1429-0551 and HE 1305+0007. HE 1429-0551 is also enriched in slow neutron-capture p…
Sc and neutron-capture abundances in Galactic low- and high-alpha field halo stars
C. K. Fishlock, D. Yong, A. I. Karakas +5
We determine relative abundance ratios for the neutron-capture elements Zr, La, Ce, Nd, and Eu for a sample of 27 Galactic dwarf stars with -1.5 < [Fe/H] <-0.8. We also measure the…
The Chemical Evolution of Fluorine in the Bulge - High-resolution K-band spectra of giants in three fields
H. Jönsson, N. Ryde, G. M. Harper +6
Possible main formation sites of F in the Universe include AGB stars, the ν-process in Type II SNe, and/or W-R stars. The importance of the W-R stars has theoretically been questio…
Metallicity Gradients in Disks: Do Galaxies Form Inside-Out?
K. Pilkington, C. G. Few, B. K. Gibson +13
We examine radial and vertical metallicity gradients using a suite of disk galaxy simulations, supplemented with two classic chemical evolution approaches. We determine the rate of…
