That's 3 in the Christmas Tree

Normal sudoku rules apply. Every row, column and box must have a complete set of the digits 1-9. Thermometers: the digits must increase from the bulb to the tip. The two thermometers meeting in box 2 meet at the star at the top of the Christmas tree, at r1c5. (The star is otherwise cosmetic). Kropki dots: cells separated by a white dot contain consecutive digits. Cells separated by a black dot contain digits in a 1:2 ratio. Not all possible dots are given. Modular lines: any three consecutive cells on a teal modular line must have one digit from each of {1,4,7}, {2,5,8}, {3,6,9}
