Mercedes Lopez - Morales, an astronomer at the Harvard - Smithsonian Center for Astrophysics, has modeled the possibilities of magnetic fields around red dwarf planets, and a picture is gradually emerging: The planets likely form in the outer parts of their solar systems and migrate in.

How such a dense planet formed is unclear, the researchers say, but it's probably the crystalline vestige of a white dwarf star whose atmosphere was stripped away by the parent pulsar.

Other astronomers find the detections convincing, although most reserve the name «planet» for bodies that form within a planetary system and orbit stars, says theorist Alan Boss of the Carnegie Institution of Washington in Washington, D.C. «They should call them «planetary - mass brown dwarfs,»» Boss says.

Cartoon showing how efficient planet migration around red dwarfs lead to the more observed planets than around sunlike stars, even though the disk is lower in mass and forms fewer planets in total.

We know that protoplanetary disks around red dwarfs are lower in mass, so we expected them to form fewer or smaller planets.

- When brown dwarfs were just a theoretical concern, astronomers differentiated those hypothetical objects from planets by how they were formed.
