The chemical evolution of the solar neighbourhood for planet-hosting stars
Marco Pignatari, Thomas C. L. Trueman, Kate A. Womack +13
Theoretical physical-chemical models for the formation of planetary systems depend on data quality for the Sun's composition, that of stars in the solar neighbourhood, and of the e…
Origin of the Metallicity Distribution in the Thick Disc
Maider S. Miranda, Kate Pilkington, Brad K. Gibson +9
Aims. Using a suite of cosmological chemodynamical disc galaxy simulations, we assess how (a) radial metallicity gradients evolve with scaleheight; (b) the vertical metallicity gra…
The Lowest Metallicity Stars in the LMC: Clues from MaGICC Simulations
Chris B. Brook, Maider S. Miranda, Brad. K. Gibson +2
Using a cosmological hydrodynamical simulation of a galaxy of similar mass to the Large Magellanic Cloud (LMC), we examine the predicted characteristics of its lowest metallicity p…
Constraining Sub-Grid Physics with High-Redshift Spatially-Resolved Metallicity Distributions
B. K. Gibson, K. Pilkington, C. B. Brook +2
We examine the role of energy feedback in shaping the distribution of metals within cosmological hydrodynamical simulations of L* disc galaxies. While negative abundance gradients…
Decoding the message from meteoritic stardust silicon carbide grains
Karen M. Lewis, Maria Lugaro, Brad K. Gibson +1
Micron-sized stardust grains that originated in ancient stars are recovered from meteorites and analysed using high-resolution mass spectrometry. The most widely studied type of st…
Chemical Evolution of the Carina Dwarf Spheroidal
K. Pilkington, B. K. Gibson
We explore a range of chemical evolution models for the Local Group dwarf spheroidal (dSph) galaxy, Carina. A novel aspect of our work is the removal of the star formation history…
The Distribution of Metals in Cosmological Hydrodynamical Simulations of Dwarf Disk Galaxies
K. Pilkington, B. K. Gibson, C. B. Brook +9
We examine the chemical properties of 5 cosmological hydrodynamical simulations of an M33-like disc galaxy which have been shown to be consistent with the morphological characteris…
The stellar metallicity distribution of disc galaxies and bulges in cosmological simulations
F. Calura, B. K. Gibson, L. Michel-Dansac +11
By means of high-resolution cosmological hydrodynamical simulations of Milky Way-like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution funct…
The Distribution of Young Stars and Metals in Simulated Cosmological Disk Galaxies
K. Pilkington, B. K. Gibson, D. H. Jones
We examine the distribution of young stars associated with the spiral arms of a simulated L* cosmological disk galaxy. We find age patterns orthogonal to the arms which are not inc…
The Chemical Evolution of Globular Clusters - II. Metals and Fluorine
Patricia Sanchez-Blazquez, Andrea Marcolini, Brad K. Gibson +3
In the first paper in this series, we proposed a new framework in which to model the chemical evolution of globular clusters. This model, is predicated upon the assumption that clu…
The Cold Gas Content of Bulgeless Dwarf Galaxies
K. Pilkington, B. K. Gibson, F. Calura +8
We present an analysis of the neutral hydrogen (HI) properties of a fully cosmological hydrodynamical dwarf galaxy, run with varying simulation parameters. As reported by Governato…
