Supermassive Black Holes (6x6 Trial Puzzle)

I created this puzzle as a test for a potential 9x9 with similar rules, and wanted to see if there is a demand for it. (If no, I will still make it sometime, but not immediately). Please leave feedback on how you found it! All feedback helps me grow as a setter and set more quality puzzles for you.
When solving, make sure you stand at least 2GM/c^2 meters away from the screen so that you do not fall into the puzzle!
Happy solving!
- Normal 6x6 sudoku rules apply
- You need to place 2 black holes in the grid. We would rather not invoke a binary black hole merger, as a result we must keep the black holes out of each others orbit. The black holes cannot share any edge of any cells, but may touch diagonally.
- Black holes are mysterious creatures and a lot is unknown. However, in this puzzle, we know that they have a singularity each, and are surrounded by an accretion disk. The singularity is a single cell, and may not have a smaller value than any of the cells in its accretion disk (the surrounding 8 cells). Altogether, each black hole is made up of 9 cells total.
- Each accretion disk obeys a different rule, one such disk is a region sum line, where box borders that divide the disk must sum to the same total. The other disk is a parity line, adjacent digits differ in parity (odd/even).
- Accompanying these objects are smaller bodies. Cells separated by a red dwarf (red dot) are in a 1:2 ratio. Cells separated by a white dwarf (white dot) are consecutive.
- Finally, there seems to be a small planet in r1c1. Please make sure this digit is odd.
- Not all red or white dwarfs are given.
Lösungscode: The digits in the region sum line accretion disk read clockwise from the top left digit AND the digits in the parity line accretion disk read in the same way.

This was a really interesting puzzle, I loved figuring it out (and would definitely play a 9x9)

Glad you enjoy! Thanks for the comment :)

I found this enjoyable. Some unique logic and satisfying solve.
Could use a shorter solve code.

Thank you for the kind words and the solve! I am glad you enjoyed, however I am not sure what the benefit of a shorter solution code would be.

So much fun! Discovering how the black holes had to fit into the grid was a joy, and then decoding which one went where was smooth. I'd love a 9x9 version!
