Neutron stars are known to have rotation periods between about 1.4 ms to 30 seconds. The neutron star's density also gives it very high surface gravity, up to 7×1012 m/s2 with typical values of a few ×1012 m/s2 (that is more than 1011 times of that of Earth). One measure of ...
Astronomersusing NASA's Swift X-ray telescope have detected a neutron star within 250 to1,000 light-years of Earth, making it the closest neutron star ever known. The object,located in the constellation Ursa Minor, is nicknamed Calvera, after the villainin the movie "The Magnificent Seven."...
In February 1987, the closest supernova to Earth in almost 400 years exploded onto the scene. Designated Supernova 1987A (SN 1987A), it resulted from the death of a massive star in the Large Magellanic Cloud, a dwarf galaxy 160,000 light-years away. In the decades since, its remnant h...

About the size of a city, a neutron star is the remnant of an exploded star whose matter is so compressed, the protons and electrons within its atoms fuse into neutrons. A teaspoon of the dense stuff would weigh about a billion tons on Earth. ...
By timing when the pulses arrived at Earth, we found that PSR J1325-6253 is in a small orbit of 1.81 d. Its orbit deviates from a circularity with one of the lowest orbital eccentricities known for a DNS system (e=0.064). The elliptical orbit advances its point of closest approach (per...

The first is from a frame co-rotating with the star to a frame just above the star's surface (a local Lorentz boost). The second trans- formation is from the star to the observer at infinity. The first transformation considers the special relativistic effects of the moving spot, such as...
Margutti's team also benefited from the star's relative closeness to Earth. Even though it was nestled in the distant dwarf galaxy called CGCG 137-068, astronomers consider that to be "right around the corner." "Two hundred million light years is close for us, by the way," Margutti said...
