Question
Stars of similar temperatures but different sizes will have:
- Same luminosities but various masses.
- Same masses but different distances.
- Various spectral types but same luminosities.
- Same spectral types but various luminosities.
Hint:
The stars with the same temperature have the same spectral type and the luminescence varies depending on their sizes.
The correct answer is: Same spectral types but various luminosities.
- The luminescence of the stars depends on their surface temperature.
- The stars with the same temperature will have the same spectral types.
- The luminescence of the stars of the same temperature varies according to the size of the stars.
