Aurora auroras is that an as-yet-undetected body around the dwarf star is throwing off material, as is the case with Jupiter and its moon Io.

Auroras are produced when the magnetosphere is sufficiently
Aurora Borealis (icebreaker) a slightly smaller and cheaper (less than 500-million-euro) version, "Aurora Slim", has been suggested by the Finnish engineering company Aker Arctic. The most prominent change from "Aurora Borealis" to "Aurora Slim" is that the insulated drilling rig is no longer present. The scientist have to rely on a mobile system and shallower boreholes of a few hundred metres instead of more than . She will also have only a single moon pool instead of two as in the original concept. Like the original concept, the vessel is designed to break level ice up to in thickness. However, the dynamical positioning
