What does Einstein's general theory of relativity tell us about two co-orbiting white dwarfs?
A) They will emit gravitational waves that carry energy and angular momentum away from the system, causing the white dwarfs to gradually spiral inward toward each other and eventually merge. B) They will emit gravitational waves that carry energy and angular momentum toward the system, causing the white dwarfs to gradually spiral away from one another and eventually fly far apart. C) They will emit gravitational waves that carry energy and angular momentum away from the system, causing the white dwarfs to quickly spiral away from one another. D) They will never interact with one another.
