Our understanding of the physics and evolution of stars has been undermined by the discovery of a light-years away neutron star. It might be composed mostly of quarks.
A new paper published in the journal Nature Astronomy shows how small the star is, with a mass of only 77 percent of the Sun.
It has a mass of less than the mass of the Sun at the same location.
Victor Doroshenko is an astronomer at Eberhard Karls University of Tbingen in Germany.
The central compact object in HESS J1731-347 is the lightest neutron star known to date and could be a strange star.
Supergiant stars, which are some of the densest objects in the universe, are usually formed after a nova.
The star's core can collapse into an object. A small amount of the star would have a mass ofPukiWikiPukiWikiPukiWikis.
This object is not in line with our known definitions.
The star is closer to us than we thought thanks to the data obtained by the European Space Agency's Gaia satellite.
According to the team, this new discovery is a possible "strange star" because it doesn't fit into our definition of a neutron star.
Strange stars are hypothetical objects that can have lower temperatures and densities of other stars.
Astronomers believe that strange stars could be behind some of the mysterious and powerful radio bursts that have not been explained.
It is an object that could change our understanding of the universe.
Doroshenko and his team wrote in a statement that the light neutron star appears to be a very interesting object.
Scientists say that an object may be a strange star made out of quarks.
The scientists spotted something that was moving 7 times the speed of light.
