How does the required core temperature for deuterium fusion compare to that needed for standard hydrogen fusion?
Answer
It requires a significantly lower core temperature (around 1 million Kelvin)
Deuterium fusion can commence at a much lower core temperature, approximately 1 million Kelvin, compared to the roughly 10 million Kelvin necessary to overcome electrostatic repulsion and begin fusing regular hydrogen ($^1 ext{H}$).
