Magnetar

Magnetic stars were the result of an electron star colliding with a proton star. They could also form in gravitational collapse when the neutrons in the core of a star were obliterated, leaving only protons and electrons. Magnetic stars had two poled, a positive and a negative. They had incredible magnetic fields which could stretch for light years and easily attract planets containing metals, as well as other magnetic stars. When such planets were drawn in, they merged to form superplanets and rocky stars. The enormous planet Polygatoa was created by a magnetic star. Sometimes, enough matter could be drawn in to create a new star.
