- | =====Results===== | + | Modelling XRB nucleosynthesis in XNET following the model of the <del>Dissertation of Lau 2012</del> Fisker 2007, using the premade model for CNO XRB. |
+ | |||
+ | Goal: 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. | ||

+ | |||
+ | * Read Paper | ||
+ | * Create network list/sunet- use premade scenario following Fisker_2007 (see references) | ||
+ | * Temperature profile- use Fisker premade scenario | ||
+ | * Determine initial molar abundances to altar ab_XRB file | ||

+ | * Use scripts to make plots- | ||
+ | * abundance plots working | ||
+ | * easier in Excel | ||

+ | * Design end objective | ||
+ | * <del>Integrate the energy generated at the surface and compare to surface photon emission</del> (goal changed) | ||
+ | * vary metallicities to identify burst conditions (see abstract) | ||
+ | * refine python scripts to [[https://github.com/xrf/talent-astro-proj2/blob/master/tso_reader.py|read output]], visualize | ||
+ | * make video with [[https://github.com/xrf/talent-astro-proj2/blob/master/plot-chart|script]] | ||

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