Neutronic

Modelling XRB nucleosynthesis in XNET following the model of the Dissertation of Lau 2012 Fisker 2007, using the premade model for CNO XRB.

• Create video of working burst nuclides chart.
• Vary initial metallicity still using Fisker thermal trajectory, see if burst still occurs.
• Vary initial H/He ratio within metallicity still using Fisker thermal trajectory, see if burst still occurs.
• Create videos of stalled burst nuclides charts.

• Code
• Presentation

• Video 1 (small nuclear network)
• Video 2 (large nuclear network)

Since the initial X-ray burst is dependent on so few nuclei, almost no configuration can stop the burst behavior in a toy model.

• Read paper
• Create network list/sunet: use premade scenario following Fisker_2007 (see references in presentation)
• Temperature profile: use Fisker premade scenario
• Determine initial molar abundances to alter ab_XRB file
• PPT 3, 4, 7

• Read paper
• Study Xnet: made a clearer set of instructions for running non-default library: rxn net instructions, ran XRB-CNO example, MS Excel eats a space column about half way down the file, was causing burst plotting errors.
• Use scripts to make plots-:
  • Abundance plots working
    • Easier in Excel
  • Animation script working
• PPT 2, 5, 6, references

• Read paper
• Design end objective
  • Integrate the energy generated at the surface and compare to surface photon emission (goal changed)
  • vary metallicities to identify burst conditions (see abstract)
• Refine python scripts to read output, visualize
• Make video with script
• PPT 8, 9, 10
