Introduction

• Observations of Type I X-ray bursts yield increasingly more detailed information about the conditions under which the burning takes place.

• Numerical models are sensitive to these precise conditions, as they affect:

  • The choice of algorithm.
  • The level of detail that can be obtained.
  • The size of the domain needed to get most of the qualitative features.

• All of these details affect the cost of the simulation.

  • Resolving the burning front and size of the envelope requires a lot of zones.
