Many stars make energy with the proton-proton cycle. 2. The CNO cycle is more efficient than the proton-proton cycle. 3. The sun's energy comes from the CNO cycle.More massive stars make energy with the proton-proton cycle. 4. The leftover mass in both the proton-proton cycle and the CNO cycle is converted to energy. 5. A helium atom is more massive than four hydrogen atoms. 6. The CNO cycle requires a higher temperature than the proton-proton cycle.arrow_forward
- The Sun is estimated to have about 5.00 billion years left in it’s “normal” (main sequence) lifetime. Assume the average “burn” rate that you computed in question #1, what % of the Sun’s current mass will have been converted at the end of it’s estimated 5.00 billion years of additional life? Actually, the Sun will lose more mass due to the solar wind, CMEs, the neutrio flux etc. the answer to number one was 3.683x10^14arrow_forwardStatus of Sun's core and its temperature (The letters correspond to the stages in Figure 21.1.) 3.

Hint: Use the small-angle formula: angular diameter (in arc seconds) 2.06 ✕ 105 = linear diameter distance 2. Suppose a planetary nebula is 3.2 pc in diameter, and Doppler shifts in its spectrum show that the planetary nebula is expanding at 31 km/s. How old is the planetary nebula in yr?
