Protostars are in the earliest stage of stellar evolution and have the lowest temperature cores compared to more evolved stars like massive main-sequence stars and white dwarfs. This is because they are still in the process of collapsing under gravity and have not yet initiated nuclear fusion in their cores, which significantly increases the core temperature.
