It is a really exciting time for Nuclear Astrophysics, with:
To fully exploit the progress in astrophysics our experimental and theoretical programmes focus on the origin of the chemical elements throughout the Life and Death of Massive Stars, as well as the impact of nuclear physics in the extreme astrophysical environments of Compact Objects and Binaries.
In our programme on the Life and Death of Massive Stars, we seek to answer two key questions:- What role do massive stars play in the Galaxy?- What is the impact of core collapse supernovae on galactic chemical evolution?
To tackle these questions we focus on the following strands of research:
The photo above show the SHARC silicon detector array at TRIUMF (left), and a representation of one model (linear chain) for the 12C Hoyle state (right)
Our work on Compact Objects and Binaries, is similarly focussed on the two key questions:- How do compact binaries contribute to the production of heavy elements?- How does the nuclear equation of state drive the structure and dynamics of neutron stars and neutron-star mergers? To tackle those key questions identified in this area, we are working on a microscopic description of the evolution of neutron-star binary systems and neutron-star mergers. This includes treatment of the high temperatures involved in these scenarios. We further investigate heavy-element production during x-ray bursts and thermonuclear supernovae and mergers.
