Using telescopic observations and spectroscopy,we can determine each of the following aspects of a star EXCEPT ONE.Which is the exception?
A) the temperature
B) the current rate of nuclear energy generation in the interior
C) the radial velocity
D) the surface composition

Question

Quizplus · Accepted Answer

We can determine the temperature of a star, its surface composition through spectroscopy, and its radial velocity through Doppler shifts in its spectrum. However, determining the rate of nuclear energy generation in the interior is much more difficult and usually requires sophisticated models of stellar structure and evolution.
