The Regulated GeAs Cycles with the New Ga(p,)Ge and Ge(p,)As Reaction Rates and Their Impact on the GS 182624 Clocked Bursts and SAX J1808.43658 Photospheric Radius Expansion Bursts
Yi Hua Lam, Ning Lu, Alexander Heger +3
The Ga(p,)Ge and Ge(p,)As thermonuclear reactions connect the ZnGa and GeAs cycles by diverting the flow of the rapid proton capture process from…
Robust inference of neutron-star parameters from thermonuclear burst observations
D. K. Galloway, Z. Johnston, A. J. Goodwin +1
Thermonuclear (type-I) bursts arise from unstable ignition of accumulated fuel on the surface of neutron stars in low-mass X-ray binaries. Measurements of burst properties in princ…
Comparison of Electron Capture Rates in the N=50 Region using 1D Simulations of Core-collapse Supernovae
Zac Johnston, Sheldon Wasik, Rachel Titus +4
Recent studies have highlighted the sensitivity of core-collapse supernovae (CCSNe) models to electron-capture (EC) rates on neutron-rich nuclei near the N=50 closed-shell region.…
The Impact of the New As(p,)Se Reaction Rate on the Two-Proton Sequential Capture of Ge, Weak GeAs Cycles, and Type-I X-Ray Bursts such as the Clocked Burster GS 182624
Yi Hua Lam, Zi Xin Liu, Alexander Heger +3
We re-assess As(p,)Se reaction rates based on a set of proton thresholds of Se, (Se), estimated from the experimental mirror nuclear ma…
The Regulated NiCu Cycles with the new Cu(p,)Zn reaction rate and the Influence on Type-I X-Ray Bursts: GS 182624 Clocked Burster
Yi Hua Lam, Ning Lu, Alexander Heger +5
During the X-ray bursts of GS 182624, "clocked burster", the nuclear reaction flow that surges through the rapid-proton capture process path has to pass through the NiCu cycles…
The efficiency of nuclear burning during thermonuclear (Type I) bursts as a function of accretion rate
Y. Cavecchi, D. K. Galloway, A. J. Goodwin +2
We measured the thermonuclear burning efficiency as a function of accretion rate for the Type I X-ray bursts of five low-mass X-ray binary systems. We chose sources with measured n…
Multi-epoch X-ray burst modelling: MCMC with large grids of 1D simulations
Zac Johnston, Alexander Heger, Duncan K. Galloway
Type-I X-ray bursts are recurring thermonuclear explosions on the surface of accreting neutron stars. Matching observed bursts to computational models can help to constrain system…
High-energy transients: thermonuclear (type-I) X-ray bursts
Duncan K. Galloway, Zac Johnston, Adelle Goodwin +1
Many distinct classes of high-energy variability have been observed in astrophysical sources, on a range of timescales. The widest range (spanning microseconds-decades) is found in…
Simulating X-ray bursts during a transient accretion event
Zac Johnston, Alexander Heger, Duncan K. Galloway
Modelling of thermonuclear X-ray bursts on accreting neutron stars has to date focused on stable accretion rates. However, bursts are also observed during episodes of transient acc…
