Africa-Press – Rwanda. <\/strong><\/span>White dwarfs are ancient stars that develop after having exhausted their nuclear fuel and expelling the majority of its outer materials. Typically, said stars carry about half the mass of the Sun and maintain a size just slightly larger than the Earth. However, that\u2019s not the case for all, it seems.<\/p>\n

Astronomers surveying the cosmos have uncovered quite the unusual and highly unexpected find: a white dwarf star similar in size to the Earth\u2019s moon that has a mass far greater than the Sun.<\/p>\n

Located about 130 million light-years from Earth, the star, named ZTF J1901+1458, is described as having an \u201cextreme\u201d magnetic field that allows it to complete one full revolution in under seven minutes.<\/p>\n

Officials determined that the newly-discovered white dwarf is 1.35 times the mass of the Sun, with a diameter that measures in at about 2,670 miles, nearly 500 miles more than the Earth\u2019s moon.<\/p>\n

At the recorded diameter, the measurement ranks the star as among one of the smallest white dwarfs tracked by astronomers. Previous record-holders were stars RE J0317-853 and WD 1832+089, both of which had diameters measuring roughly 3,100 miles.<\/p>\n

Astronomers believe that the white dwarf is the result of two less massive, orbiting white dwarf stars that eventually collided with one another and merged. It\u2019s also thought that the subject may later evolve into a neutron star.<\/p>\n

\u201cThis is highly speculative, but it\u2019s possible that the white dwarf is massive enough to further collapse into a neutron star,\u201d Ilaria Caiazzo, the lead author of the study, said in a statement released by the Keck Observatory.<\/p>\n

Although the star was discovered by the Zwicky Transient Facility at Caltech\u2019s Palomar Observatory, several additional observatories, including Keck, aided in astronomers\u2019 efforts to uncover details of the find.<\/p>\n

\u201c[The star] is so massive and dense that, in its core, electrons are being captured by protons in nuclei to form neutrons. Because the pressure from electrons pushes against the force of gravity, keeping the star intact, the core collapses when a large enough number of electrons are removed,\u201d Caiazzo added.<\/p>\n

As the discovery has only marked the beginning of the investigation into the \u201cvery special\u201d star, officials intend to use the revelation to further understand the occurrence of white dwarfs.<\/p>\n

The team\u2019s findings were published in the July issue of the journal Nature.<\/p>\n
