D) the star's radial motion

Question

Quizplus · Accepted Answer

By examining a star's spectrum, we can determine its spectral class, luminosity class, and radial motion through the Doppler effect. However, we cannot directly determine a star's neutrino flux through its spectrum. Neutrinos are subatomic particles that are difficult to detect and are not usually included in spectral analysis.
