A solar model is used to calculate the expected temperature and density at all depths within the Sun. These results are then used to calculate the expected fusion rate within the Sun. We have confidence that the model is correct because it agrees with the observed characteristics of the Sun. Which of the following observations can be used to check that we really do know the Sun’s internal fusion rate?.
A. Measurements of the varying number of sunspots on the Sun over time.
B. Measurements of the Sun’s total energy output into space.
C. Observations of neutrinos coming from the Sun.
D. Observations of the total X-ray emission from the Sun’s corona.
E. Measurement of the Sun’s mass
