The chemical makeup of a star's surface is usually inferred by:
A) theoretical methods, considering the evolution of the star.
B) spectroscopy of the light emitted by the star.
C) measuring the chemical elements present in the solar wind.
D) taking a sample of the star's surface with a space probe.

Question

Quizplus · Accepted Answer

Spectroscopy of the light emitted by the star allows astronomers to determine which chemical elements are present in the star's atmosphere. Different elements absorb and emit specific wavelengths of light, creating unique spectral lines that can be used to identify the chemical makeup of a star's surface. This technique is commonly used in astronomy to study the properties of stars and other celestial objects.
