The word 'evolution' has a Darwinian unambiguous meaning in science, that = descent modification selection. To describe stellar change as evolution is wrong, slovenly imo, that is unless one See's Darwin's mechanism and a process.

Stellar evolution refers to the birth, life and death of a star. It has a definite meaning in astrophysics. A lot of astrophysics books are titled "stellar evolution".
The word evolution is not a word used exclusively in biology; evolution in general does not refer to the theory of evolution, but to anything that changes over time usually via specific processes.
The Oxford Dictionary has it as the theory of evolution as 1, and "the gradual development of something" as 2.
