Unusual auroras similar to those on Earth can be found on planets orbiting a special type of neutron star.
On Earth, auroras occur as a result of the impact of charged particles from the Sun on our atmosphere. These particles cause gases in the atmosphere to glow, and the resulting colorful phenomenon can be observed. The authors of the study, published on the arXiv preprint server, believe similar auroras occur on planets orbiting pulsars. ScienceAlert writes that these events can be detected.

When a massive star dies and can no longer create heavy chemical elements during nuclear fusion in its core, a supernova explosion occurs. The star explodes and disintegrates almost completely, leaving behind a very dense core consisting only of neutrons. This is a neutron star that rotates very quickly around its axis. If such a star periodically releases streams of various types of radiation into space, it is called a pulsar.
Important
Using modelling, scientists have suggested that strange aurorae that are somewhat similar to those on Earth appear on planets orbiting pulsars.
Most pulsars do not have planets orbiting them, but about 0.5% of pulsars are thought to have planetary moons around them. Scientists have created simulations of the magnetic interaction between pulsars and their planets to estimate the amount of electromagnetic radiation released.
In their study, scientists looked at millisecond pulsars and the planets around them and looked at potential options for detecting planets using radio emission. Researchers examined two potential planets that do not have their own magnetic fields. One object has a conductive surface and the second has an electrically neutral surface.
Scientists assumed that the frequency of the radiation flux density would be above the level to be absorbed by the plasma, but below the level to be blocked by the planet’s ionosphere. As a result, it happened like this. As modeling shows, planets orbiting millisecond pulsars can be seen using modern radio telescopes. And of course, auroras can be detected on them.
As I already wrote FocusScientists have developed a new method to detect dark matter and believe it is responsible for the glow on Jupiter’s night side.
Moreover Focus He wrote that as a result of the influence of the influx of solar particles, the size of the magnetosphere and atmosphere of Mars has increased significantly.
