On the origin of fluorine in the Milky Way

A. Renda, Y. Fenner, B. K. Gibson +6

The main astrophysical factories of fluorine (19F) are thought to be Type II supernovae, Wolf-Rayet stars, and the asymptotic giant branch (AGB) of intermediate mass stars. We pres…

Contrasting the chemical evolution of the Milky Way and Andromeda galaxies

Agostino Renda, Daisuke Kawata, Yeshe Fenner +1

The chemical evolution history of a galaxy hides clues about how it formed and has been changing through time. We have studied the chemical evolution history of the Milky Way (MW)…

Modelling self-pollution of globular clusters from AGB stars

Y. Fenner, S. Campbell, A. I. Karakas +2

A self-consistent model of the chemical evolution of the globular cluster NGC 6752 is presented to test a popular theory that observed abundance anomalies are due to ``internal pol…

Constraints on Early Nucleosynthesis from the Abundance Pattern of a Damped Ly-alpha System at z = 2.626

Yeshe Fenner, Jason X. Prochaska, Brad K. Gibson

We have investigated chemical evolution in the young universe by analysing the detailed chemical enrichment pattern of a metal-rich galaxy at high redshift. The recent detection of…

Photometric Properties of White Dwarf Dominated Halos

H. -c. Lee, B. K. Gibson, Y. Fenner +5

Using stellar population synthesis techniques, we explore the photometric signatures of white dwarf progenitor dominated galactic halos, in order to constrain the fraction of halo…

The Galactic Habitable Zone and the Age Distribution of Complex Life in the Milky Way

Charles H. Lineweaver, Yeshe Fenner, Brad K. Gibson

We modeled the evolution of the Milky Way to trace the distribution in space and time of four prerequisites for complex life: the presence of a host star, enough heavy elements to…
