I will outline how nearly all of the elements essential to you are produced in the evolution of low-mass and high-mass stars and in white-dwarf binaries. All the essential elements except for iodine, that is. The story of where did iodine come from along more common materials like platinum (yes, platinum is more common in the Universe) was a mystery for 60 years between when B2FH first...

We discuss observations of neutron stars and neutron star mergers and how these depend on the equation of state and other properties of dense neutron rich matter. We also discuss some related laboratory experiments with neutron rich nuclei.

The r-process occurs in neutron star mergers. This has been confirmed by the observation of the decay of neutron rich radioactive nuclei as a kilonova light curve after the neutron star merger detected with gravitational waves GW170817. We study the nucleosynthesis and kilonova light curves from different ejecta of neutron star mergers discussing the astrophysical and nuclear physics...

Last August marked the first observation of gravitational waves and electromagnetic signals from the merging of two neutron stars sending ripples through the astrophysics, atomic physics, nuclear physics and gravitational wave communities. In some components of neutron star merger ejecta fission is thought to re-cycle the material and impact the abundances. I will focus the talk on the...

The past decade or so has seen great progress in applying effective field theory ideas and non-perturbative many-body methods towards the quantitative prediction of the structure of light nuclei. I will give a brief overview of this program and discuss work in progress to extend this success up the nuclear chart beyond A=100, with a focus on binding energies, beta decay, and the limits of stability.

The origins of the heavy elements have continued to be one of the grand challenges for all of science in the 21st century. The recent observation of gravitational waves from two neutron star mergers simultaneously with the spectroscopy showed that rare earth elements are in fact being made in neutron star mergers. While questions remain about sufficient numbers of mergers to account for the...

The new beam delivery capabilities of the ARIEL facility offer many exciting science opportunities. Among these new possibilities is access to isotopes of particular importance to characterizing the rapid-neutron capture process. Understanding the mechanisms responsible for creating the elements in our universe is one of the most compelling open questions in contemporary science. I will give...

The goal of the TI-STAR (TIGRESS Silicon Tracker Array) project is to build a new tracking silicon detector, combined with an extended gas target that will fit in the TIGRESS gamma detection array at ISAC-II. Different from (active) gas detectors, TI-STAR will use a silicon tracker with an ultra-thin first silicon layer to track the emitted recoiling nuclei.
In this talk we will focus on...

ARIEL will dramatically increase the availability of radioactive ion beams by harvesting isotopes from three target stations simultaneously - a worldwide unprecedented technology - enhancing the scientific output of the laboratory. For the first time, high-power electrons (up to 500 kW) will be converted into gamma rays inducing photonuclear reactions in one target, while two others are being...
