What are the similarities between a black hole accretion disk and the sun corona sphere?
The surface of the sun is 5000 degrees.
The temperature of the Corona is over million degrees.
Like a Black Hole, the sun attracts mass from space. Like a black holes accretion disk, energy is released from the accretion disk. The attraction sphere is huge.
How much mass is the Sun attracting and converting to energy?
Is the incoming mass being converted to E=MC^2 ?
The temperature of the Corona is over million degrees.

Basically two entirely different things.
The corona is largely a magnetic feature and the accretion disk is a gravitational feature.
The amount of energy the sun creates by converting mass falling into it into energy is negligible, almost nothing, really, compared to the nuclear fusion at its core. Mass falling in (rocks, asteroids, comets) is not converted to energy via E=MC^2.
Interesting article on the corona the other day, however. They think they've solved why it's a million degrees:

Is there magnetic loops from the surface of the sun to the Corona?
If hydrogen matter from space falls into the Sun accretion disk then the matter would be convert into energy and result in millions of degrees of temperature. The additional power source may be dark current according to the electric sun theory.
