4213. Advances in Experimental Nuclear Astrophysics

Annika Lennarz (TRIUMF)

Nuclear Physics / Physique nucléaire (DNP-DPN)

Invited Speaker / Conférencier(ère) invité(e)

Explosive stellar events, such as X-ray bursts, novae, and supernovae, play a pivotal role in synthesizing the chemical elements observed in our galaxy and on Earth. The field of nuclear astrophysics seeks to unravel the mysteries behind the origin of the chemical elements and understand the underlying nuclear processes governing the evolution of stars. Particularly, the investigation of...

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Neutron star mergers are an ideal environment for rapid (r-process) neutron captures to take place that lead to the production of neutron-rich nuclei far from the valley of stability. This is one encouraging site to investigate for where abundances of the heaviest elements in our Solar System and beyond are thought to have come from. We explored the r-process regime in mergers through the...

4226. (G*) The Equation of State of Ultra-Dense Matter and its Implication for the Diffuse Neutrino Background

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The equation of state of ultra-dense matter, which gives a relation between microscopic and macroscopic quantities of ultra-dense objects and describes the core of the most energetic events of the universe, remains incompletely understood, particularly under extreme conditions such as high temperatures (i.e. in the order of ~10 MeV). In order to compute the hydrodynamic simulation of a binary...

4438. Exotic nuclear superfluidity in heavy nuclei

Georgios Palkanoglou (TRIUMF)

Nuclear Physics / Physique nucléaire (DNP-DPN)

Oral (Non-Student) / Orale (non-étudiant(e))

Nuclear pairing, i.e., the tendency of nucleons to form pairs, has important consequences to the physics of heavy nuclei and compact stars. While the pairing found in nuclei typically happens between identical nucleons and in spin-singlet states, the exotic spin-triplet and mixed-spin pairing phases have also been hypothesized. In this talk, I will present new investigations confirming the...
