Question

Quizplus · Accepted Answer

Mass transfer occurs in binary systems when one star (typically a giant star) swells to reach its Roche lobe, which is the point at which gravitational forces from the other star in the system pull material away from the giant. This can lead to the transfer of matter from one star to the other, and can have important consequences for the evolution of both stars. Therefore, the correct choice is D) Roche Lobe. Mass transfer in binaries occurs when one star swells beyond its Roche lobe, which is the gravitational boundary that determines whether material will remain bound to the star or be transferred to its companion. Therefore, the correct choice is D) Roche Lobe.
