Ramblings

Sometimes I explore some ideas to a sufficient depth that it seems worthwhile for me to archive the technical derivations even if the idea itself does not immediately produce a publishable result. This page, which has a simple outline layout, provides links to these various pages of technical notes.

  1. Toroidal configurations & related coordinate systems
  2. Relationship between HNM82 models and T1 coordinates
  3. Orthogonal Curvilinear Coordinates
  4. Playing with the Spherical Wave Equation
  5. Analyzing Azimuthal Distortions
    1. Summary for Hadley & Imamura
    2. Detailed Notes   🎦
    3. Supplementary database generated by the Hadley & Imamura collaboration
    4. Large supplementary dataset accumulated by the Hadley & Imamura collaboration
    5. YouTube videos that supplement simulations of J. W. Woodward, J. E. Tohline, & I. Hachisu (1994)
    6. Stability Analyses of PP Tori
    7. Stability Analyses of PP Tori (Part 2)
  6. Integrals of Motion
    1. Old discussion
    2. T3 Coordinates
      1. Special (quadratic) case: Joel's Derivation vs. Jay's Derivation
    3. Killing Vector Approach; Jay Call's related Talk page
    4. Characteristic Vector for T3 Coordinates
    5. T4 Coordinates (Abandoned by Joel 7/6/2010 because non-orthogonal)
  7. Marcello's Radiation-Hydro Simulations
    1. Determining Code Units
    2. Summary of Scalings
    3. Initial Temperature Distributions
  8. Photosphere of Stably Accreting DWD
  9. Initial Effort to Explain Jay Call's Hybrid Scheme in the Context of Zach Byerly's Dissertation
  10. Exploring the Properties of Radial Oscillations in Pressure-Truncated n = 5 Polytropes
  11. Instabilities Associated with Equilibrium Sequence Turning Points
  12. Searching for Additional Eigenvectors for Zero-Zero Bipolytropes
  13. Investigation Resulting from a July, 2013 Discussion with Kundan Kadam
