What is the primary limitation of using the transit method for exoplanet detection?.
- A.It can only detect large exoplanets.
- B.It requires precise measurements of star brightness.
- C.It cannot determine the exoplanet's atmosphere.
- D.It is ineffective for distant stars.
Model answer
What a good answer should say
- It cannot determine the exoplanet's atmosphere.
Explanation
Why this works
The evidence indicates that while the transit method is effective for detecting exoplanets, it primarily measures changes in brightness and does not provide direct information about the atmosphere of the exoplanet. The implication is that additional methods are needed to analyze atmospheric composition.
Thus, the conclusion is that while the transit method is valuable, it has limitations in atmospheric studies.
