astrophysics - Are there any electrons inside the sun / a star?

Yes, there are electrons inside stars, they have not gone anywhere.

I must say your new theory of electromagnetic force does not make any sense to me, but there are actually a few cases where electrons "disappears" from a star:

First off, the nuclear fusion of 4 hydrogen atoms into one helium atom actually consumes electrons. Let us count the particles before and after:

Before:

• 4 electrons -4


• 4 protons +4

After:

• 2 electrons -2


• 2 protons +2


• 2 neutrons 0

Please note that the overall charge has not changed, and can not possibly do that by any means. The charge is always preserved.

The other way electrons can disappear from a star is through the formation of a neutron star. There, the particles has are pressed together so strongly that the protons and electrons have merged into neutrons. Note how the charge is preserved here too.
