By analyzing a star’s spectral signature, what key characteristics can astrophysicists deduce?

Answer

Its surface temperature, chemical composition, and even its speed relative to Earth.

The specific distribution of radiation across the electromagnetic spectrum acts as a spectral signature, providing direct information about the star's surface temperature, what elements it comprises, and its relative motion.
