Galactic 26Al traces metal loss through hot chimneys
(2021-02-01)
Radioactive 26Al is an excellent tracer for metal ejection in the Milky Way, and can provide a direct constraint on the modelling of supernova feedback in galaxy evolution. Gamma-ray observations of the 26Al decay line ...
A Minimum Dilution Scenario for Supernovae and Consequences for Extremely Metal-Poor Stars
(2020-11-01)
To date no metal-free stars have been identified by direct observations. The most common method of constraining their properties is searching the spectra of the most metal-poor stars for the chemical elements created in ...
The Origin of Elements from Carbon to Uranium
(2020-09-15)
To reach a deeper understanding of the origin of elements in the periodic table, we construct Galactic chemical evolution (GCE) models for all stable elements from C (A = 12) to U (A = 238) from first principles, i.e., ...
