13. Manraj Shergill: Investigating the 38K(p,γ)39Ca Reaction Rate for Classical Novae

Manraj Shergill (McMaster University)

01/05/2024, 11:00

This research investigates the 38K(p,γ) 39Ca reaction rate, a crucial process in classical novae nucleosynthesis. Classical novae, characterized by sudden brightness surges followed by fading, result from explosive hydrogen-rich material ignition on white dwarf stars. Notable discrepancies between observed and predicted abundances of Ca and Ar in nova ejecta underscore the necessity of...

15. Maude Larivière: Thallium-208 as a real-time signal for probing heavy element synthesis

Maude Larivière (UBC / TRIUMF)

01/05/2024, 11:20

Understanding the formation of the heaviest elements has long been a pivotal inquiry and recent progress spurred by LIGO's detection of gravitational waves now lead us to examine kilonovae as crucial markers in unraveling the processes behind the synthesis of those elements. Notably, the emission spectra of MeV gamma rays could lead to strong insight in the identification of individual...

5. The 7Be(a,g) reaction and the neutrino-p process

Alan Chen (McMaster)

02/05/2024, 11:00

The nu-p process has been proposed to happen in the neutrino-driven winds of core-collapse supernovae, and its nucleosynthesis may help explain the origin of several p-process elements. This nucleosynthesis has been shown in reaction sensitivity studies to be affected by the 7Be(alpha, gamma)11C reaction rate. This presentation will discuss a measurement of 7Be(alpha, gamma) resonance...

6. Commissioning of SHARC-II at EMMA to measure the impact of isomeric states in nova explosions

Dr Louis Wagner (TRIUMF)

02/05/2024, 11:20

Nuclear reactions play a pivotal role in the understanding of astrophysical phenomena, providing key insights into the processes occurring within stars, supernovae, and other celestial bodies. Especially experiments with radioactive isotope beams (RIB) in inverse kinematics are a vital tool to get direct information on cross-sections of astrophysical important nuclear reactions with quickly...

7. Bound-state beta-decay of 205Tl and its impact on s-process nucleosynthesis

Guy Leckenby (TRIUMF)

02/05/2024, 11:40

Lead-205 initially looks like a very promising candidate to be used as a chronometer for the early Solar System due to its unique position among astrophysically short-lived radionuclides as an s-only isotope probing the termination of the s process [1]. Unfortunately, the 2.3 keV 1/2− first excited state in 205Pb reduces the half-life in stellar environments by around 6 orders of magnitude,...

26. On possible observational signatures of i-process nucleosynthesis in presolar dust grains

Pavel Denissenkov (University of Victoria)

03/05/2024, 11:15

Multiple signatures of nucleosynthesis in asymptotic giant branch stars, classical novae, and supernovae have been revealed by analyzing CNO, Al, S, Ca, Ti, Ba, and other isotopic abundance ratios in presolar dust grains. I will show that in some grains the measured Zr, Mo, and Ru isotopic ratios can be interpreted as possible signatures of i-process nucleosynthesis.

27. (*R) Mass Ejection from Neutron Star Mergers

Rodrigo Fernandez (University of Alberta)

03/05/2024, 11:40

The coalescence of neutron stars, either among themselves or with black holes, generates significant gravitational and electromagnetic waves, and is a key site for r-process element production. The ejection of mass during and after these mergers shapes the heavy element yield and electromagnetic signal, involving a complex interplay of processes and dependencies. This talk will provide an...
