What type of data does the radial velocity method primarily rely on?.
- A.Photometric data from light curves
- B.Spectroscopic data from star spectra
- C.Astrometric data from star positions
- D.Thermal data from infrared observations
Model answer
What a good answer should say
- Spectroscopic data from star spectra
Explanation
Why this works
The evidence shows that the radial velocity method uses spectroscopic data to analyze the star's spectrum for shifts in spectral lines. This analysis reveals the star's motion and indicates the presence of orbiting planets.
Thus, the implication is that spectroscopic data is crucial for this detection method, leading to the conclusion that it primarily relies on this type of data.
