As my audience already knows, the cores of stars electro-deposit and chemically deposit material into their interiors forming cores and internal solid/liquid structures as they evolve. These interior structures are the "planets/exoplanets" which are formed as the stars evolve.
Here is an excellent paper on the electrodeposition of nickel, includes some really good stuff on current density and the time required to form layers based on current density.
Might as well add this statement to continue on theory development. I can literally find all writings I have with "stellar metamorphosis", now I can use "stars are electrochemical" and find my stuff everywhere too. If anybody wants to help, go for it.
