A) stellar masses
B) distance of the stars from Earth
C) age of the stars
D) surface temperature of the stars

Question

Quizplus · Accepted Answer

By studying the orbital characteristics of binary stars, such as their period and separation, astronomers can calculate the mass of each star using the laws of gravity. This is an important parameter in understanding the evolution and properties of stars. The other options (B, C, and D) cannot be directly derived from the study of binary stars without additional information or observations.
