Pulsars are maybe the most accurate timekeepers in the entire universe. The pulsars themselves are actually quickly spinning neutron stars. Neutron stars are ultra-dense balls of atomic matter, usually no bigger than a few miles across with a mass a few times that of the Sun..
When these neutron stars spin they blast out beams of radiation that draw circle the sky. Developing a pulsar if the Earth occurs to lie on one of those circles then we see a regular flashing from those beams of radiation.
A group of astronomers have used a model of earthquakes to understand glitches in the timing of pulsars. Their results recommend that pulsars might have interiors that are far complete stranger than can be thought of.

Pulsars will keep precise rhythm for extremely extended periods of time. Sometimes they are understood to glitch, when they unexpectedly move from one rotation rate to another.
Astronomers do not fully comprehend what causes the glitches, however recently a group of researchers created a design of how glitches operate. The model is based upon earthquakes. Earthquakes have many causes, but one of them is when too much tension and pressure constructs up between tectonic plates and the crust of the Earth buckles under the pressure. That results in an earthquake and a resettling of the product in the Earth.
When it pertains to neutron stars, their complex interiors can also go through huge pressures, with parts of the neutron star product pushing up against other parts. If the pressure ends up being excessive, the neutron star reorganizes itself, setting off a starquake and a realignment of its own interior. With the new circulation of mass within the neutron star a brand-new rotation rate emerges.
The scientists used this earthquake design to try to identify what is at the interior of neutron stars. The deep cores of neutron stars might be neutrons in a highly unique state, or a more degenerate type of matter made almost completely of strange quarks.
The researchers found that the design of the neutron star interior that included unusual quarks was much better able to produce glitches through a starquake system..
Astronomers will need to make more observations to test this concept, but it demonstrates how the observational functions of neutron stars can offer us tips regarding their mystical interiors.
