Here is the latest Hieroglyph Investigation - with reasoning to support it - as requested.
...
When Sign Lists (such as those of Sir Alan Gardiner) are referenced for similar glyphs and their etymology employed, the original context is revealed and a compelling translation can be made.
I only found one potential bit of reasoning, that one quoted above. What sign lists? How did these lead to the conclusion that the circle is a compact disk and _not_ a DVD, record, laser-disk, wheel, etc.?
nowhere in history has the sun ever been recorded as having a hole in the middle.
What you've shown doesn't have a hole in the middle. A dot isn't a hole. it could be the axle of a wheel, or not even a picture of anything, or simply a place to put the needle of a compass used to draw the circle.
