The most important neutron star in the Milky Way may become a black hole in "fat"

According to the latest observations, astronomers confirmed that so far, the heaviest neutron star PSRJ0952-0607, which has so far, is about 2.35 times the quality of the solar, and rotates 707 times per second. It almost crushed and devoured the entire quality of its companion.

The neutron Star PSRJ0952-0607 is the most density of celestial body in the scope of the Earth's observation. Such a neutron star who devoured his companion was also called the "black widow" pulse star (one of the neutron stars) by astronomers.

Confirm the quality of the "Black Widow" pulse star can help scientists determine the quality division between the large neutron star and the smallest black hole.

With the core of the most density except the black hole

Romani, a professor of celestial physics at Stanford University in the United States, pointed out that the density of neutron stars is very high, and the quality of neutron stars per 1 cubic inch exceeds 10 billion tons. Their core is the most density except the black hole in the universe.

Astronomers generally believe that when a star quality is greater than about 1.4 times solar quality, a dense, compact neutron star is formed when its life collapses at the end of its life. Both were crushed together. These neutron stars are rotating. Although they cannot be seen under the visible light waves because they are too dim, they will emit radio waves, X -rays, and even gamma rays -they flicker when rotating Essence

The neutron star becomes "lonely" due to the swallowing companion

Feli Pingke, a special -appointed professor of astronomy professors of the University of California, said: "As the neutron star evolves and begins to become a red superstar, material overflows to the neutron star, which makes the neutron star rotate. The wind began to blow out from the neutron star. Then the wind was blown to the companion star and began to peel off its material. Over time, the quality of the accompanying star dropped to the quality of the planet. The formation of the millisecond pulse star of 'loneliness', they did not' loneliness' at first, but they gradually evaporated their companions, so they became 'lonely. "PSRJ0952-0607 extremely weak companion star supported this statement saying Essence

In the double star system where PSRJ0952-0607 is located, the accompanying star (now only 20 times the quality of Jupiter) is distorted by the quality of the neutron star and is locked by the tide. It is a bit hotter, and the brightness can be seen in a large telescope.

Scientists are continuing to look for the "black widow" pulse and similar neutron stars that are closer to black holes. If you can't find it, then 2.35 times the quality of the sun is the real neutron quality limit, because more than this limit, they will become a black hole.
