## 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. Relationship between HNM82 models and T1 coordinates
2. Orthogonal Curvilinear Coordinates
3. Playing with the Spherical Wave Equation
4. Analyzing Azimuthal Distortions
5. 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)
6. Marcello's Radiation-Hydro Simulations
7. Photosphere of Stably Accreting DWD
8. Binary Polytropes
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. Derivations Related to Ledoux's Variational Principle
13. More on Zero-Zero Bipolytropes
14. Analyzing Five-One Bipolytropes
15. On the Origin of Planetary Nebulae (Investigation Resulting from a July, 2013 Discussion with Kundan Kadam)</lli>
16. Looking outward, from Inside a Black Hole
17. Radial Dependence of the Strong Nuclear Force
18. Dyson (1893a) Part I:  Some Details
20. Saturn
21. Doctoral students Tohline has advised over the years
