Astrophysicists use a variety of techniques to study stars, including:
* Observing starlight: Telescopes collect light from stars, allowing astrophysicists to analyze the spectrum of light and determine the star's temperature, composition, and motion.
* Modeling: Astrophysicists create computer simulations to understand how stars form, evolve, and eventually die.
* Theoretical calculations: Mathematical models help astrophysicists predict the properties of stars and test theories about their behavior.
While "astronomer" is a broader term that encompasses the study of all celestial objects, "astrophysicist" specifically focuses on the physics and chemistry of stars.
