We have decided to analyze the accretion onto a neutron star just up until the hydrogen burning begins. We'll first attempt this as an adaptation to the Bondi accretion problem with a solid sphere near the origin (also relevant to the problem of infall onto the proto-neutron star during core collapse). If we're successful, we'll try an accretion disk in 2D with polar geometry.

• Input Person (Sarah Schwartz)
  • [ ] Looking up accretion rates for
    • [ ] X-ray bursts
    • [ ] Novae
  • [ ] Density of in falling material
  • [ ] Masses of objects
  • [ ] Alpha parameter
• Code Person (Justin Brown)
  • 2D
    • [X] Get the VH-1 polar model working.
    • [X] Set up accretion
    • [X] Implement gravity
    • [ ] Implement an alpha viscosity model.
• Analysis Person (Amber Lauer)
  • [x] Get visualization working
    • [x] Install NetCDF

/-visit on ubuntu/linux was a quagmire, went with windows virtualbox installation :(

• [x] Gathering the initial conditions for novae and X-ray bursts

1. have average values for NS and WD, time permitting will constrain to single case and derive from scratch

• [ ] Determine the input abundances
• [ ] Build the nuclear network for the problem
• [ ] Take output from the codes and determine when hydrogen burning begins
