White Dwarfs Eat More Planetary Debris Than Thought, But Magnetic Fields Hide It
Planetary debris disks around white dwarfs appear to be more plentiful than thought. That's because some white dwarfs are magnetic, and those magnetic fields create patches of metallic debris near the stars' poles, where it's more difficult to detect. This leads to an underestimation of debris, something new research is trying to correct.
