![]() On these planets, the polarised radio waves come from the regions where we see aurorae (which on Earth are also called the northern and southern lights). This is rare in dwarf stars but it’s a known feature of radio emission from Jupiter and Saturn. UV Ceti’s pulsed waves have a special property called elliptical polarisation. Small stars called pulsars make pulses in a similar way, but UV Ceti is not a pulsar. Zic’s team thinks the star continuously beams radio waves into space and the beam flashes across Earth each time the star turns. The pulses were there, coming every 5.4 hours, which is how long the star takes to rotate. ![]() ![]() A schematic diagram modelling the ionizing radiation field over the South Galactic Hemisphere of the Milky Way, disrupted by the Seyfert flare event.
