Which major perturbation can occur to a close binary system and radically alter the evolution and behavior of the two individual stars?

Question

Quizplus · Accepted Answer

Transfer of matter from one star to its companion can drastically alter the evolution and behavior of both stars in a close binary system. This can lead to changes in their mass, size, luminosity, and even trigger events such as supernovae or the formation of exotic objects like black holes or neutron stars. The transferred material can also change the chemical composition of the stars, affecting their spectral lines and making it easier to study their properties. The other options may have some impact on the system, but not as significant as the transfer of matter.
