### Example 3
> "It blows off a wind of matter and loses mass. Since the stars’ gravity depends on their masses, as the big star loses mass the orbits get a little wonky, becoming more elliptical. But when the massive star swells, it gets so big the two become a contact binary. A lot of the material leaving the higher mass star gets dumped on the red dwarf, which starts to grow. Eventually, the big star loses most of its mass and becomes a white dwarf, while what USED to be the lower mass star has grown, and now might be more massive than the other"
