- B.There are multiple exoplanets orbiting the star.
- C.The star is variable in brightness.
- D.The star is in a binary system.
Model answer
What a good answer should say
- There are multiple exoplanets orbiting the star.
Explanation
Why this works
The evidence shows that multiple dips in a light curve indicate that more than one exoplanet is transiting the star at different times. This suggests a complex system with multiple orbiting bodies.
The implication is that such systems can provide insights into the dynamics of planetary formation and interaction. Therefore, the conclusion is that light curves can reveal the presence of multiple exoplanets in a star system.
