The n-process in Core-Collapse Supernovae featuring Marco Pignatari (Konkoly Observatory) (Opens in a new window)

Online

Seminars

The n-process is a neutron-capture process activated in Core-Collapse Supernovae (CCSNe), when the Supernova shock is passing through the deepest He-rich layers of the massive star progenitor. The peak neutron density generated is typically larger than 1018 neutrons cm-3, and the dominant neutron source is the Ne22(alpha,n)Mg25 reaction where the Ne22 available was left in the ashes of the hydrostatic convective He shell.

The Viability of Novae as Sources of Galactic Lithium featuring Alex Kemp (KU Leuven, Belgium) (Opens in a new window)

Online

Seminars

Understanding the behavior of white dwarfs in interacting binary systems is critical to determining the rates, distributions, and chemical contributions from transients such as novae and type Ia supernovae. In this talk I will be presenting results from my recent work on novae, which combines population synthesis (binary_c) and galactic chemical evolution modeling (OMEGA+).

Studying the origins of the heavy elements through neutron capture. Aaron Couture, LANL (Opens in a new window)

Online

Seminars

Understanding how the heavy elements came into being in the universe presents one of the greatest challenges in nuclear physics and astrophysics.  For some time we have known that elements beyond iron on the periodic table must have been made through neutron-induced reactions, but the environments where they are made and what they can tell us about this history of our galaxy remain a mystery.

Neutron-upscattering enhancement of the triple-alpha process featuring Jack Bishop (Texas A&M University) (Opens in a new window)

Online

Seminars

Carbon is produced in stars mainly via the triple-alpha process where three helium nuclei fuse to form an excited state of carbon-12 known as the Hoyle state. This is a nuclear resonance (an excited form of a nucleus) that has properties that guide the rate that the triple alpha process takes place. Primarily, the key property is how often the Hoyle state is able to lose energy and end up in the ground state of carbon-12 – known as the radiative width.

ICONS workshop 2019 - Investigating Crusts of Neutron Stars (Opens in a new window)

Amsterdam, Netherlands

Workshops & Conferences

This is a CeNAM supported workshop that aims to bring together different areas of research that all involve studies of heated neutron star crusts. This includes observations of different manifestations of neutron stars, theoretical calculations and simulations, and nuclear experiments. One of the primary goals of this dedicated workshop is to have a facilitated discussion about the puzzling source of shallow crustal heating, and what observations/experiments/calculations are needed to move forward.
