Multiple choice

What is asteroseismology?

  1. The study of the internal structure of stars using their oscillations

  2. The study of the magnetic fields of stars

  3. The study of the chemical composition of stars

  4. The study of the evolution of stars
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Asteroseismology is the study of the internal structure of stars using their oscillations. By observing the way stars oscillate, astronomers can learn about their density, temperature, and composition.
