103. Nuclear structure for X-ray burst models via beta decay at FRIB

Christopher Wrede (Michigan State University and Facility for Rare Isotope Beams)

Invited speakers

Type I X-ray bursts are frequent transient events observed in the Milky Way using space-based X-ray telescopes. Each burst results from a thermonuclear explosion on the surface of an accreting neutron star in a close binary system. Along with various astrophysical parameters, X-ray burst models are sensitive to nuclear uncertainties. Among the most significant nuclear uncertainties identified...

21. Probing explosive nucleosynthesis with radioactive beams

Artemis Tsantiri (University of Regina)

Contributed Talks

Explosive astrophysical environments, such as X-ray bursts, novae and supernovae govern nucleosynthesis on the proton-rich side of the valley of stability. In these sites, nucleosynthesis proceeds mainly through p- and α- induced reactions, as well as photodisintegration reactions that push the nuclear flux away from the valley of stability. Modeling these environments requires detailed...

116. Direct Neutron Capture Measurements with a Storage Ring

Iris Dillmann (TRIUMF)

2026-07-28, 9:50 a.m.

Contributed Talks

Neutron capture reactions are fundamental to understanding the synthesis of elements heavier than iron in stellar environments, occurring through the slow (s), intermediate (i), and rapid (r) neutron‑capture processes. While neutron‑capture cross sections along the valley of stability—particularly for stable or long‑lived isotopes—have been extensively studied, direct measurements on...

155. ORRUBA: two decades of discovery

Steven Pain (ORNL)

2026-07-28, 10:10 a.m.

Contributed Talks

ORRUBA (the Oak Ridge Rutgers University Barrel Array) comprises the largest suite of highly-segmented silicon detectors for radioactive beam physics in the US. It was initially conceived as a standalone ~300-channel detector array for measuring (d,p) reactions on fission fragments around the Coulomb barrier. Initial experiments were performed in 2006, including the first measurement of the...
