Hypotheses

WT: galactic electric currents thru stars lights them up.

DES: excess positive charges exit the Sun, causing ohmic heating.

CLC: two models (conventional vs. exotic stars)

Std: Fusion in the core by gravitational pressure, releasing heat.

KB: Internal electromagnet, releasing heat, electrons and protons.

MM: Neutron decay releasing heat, electrons and protons from neutronium core.

BC: Aether from galactic center forming and releasing electrons in hollow solid iron globe.
