Typical magnetic fields on neutron stars are 10 12 times stronger than the Sun's magnetic field. A small number of neutron stars have magnetic fields 10 14 times the Sun's magnetic field. These ultra-strong magnetic field neutron stars are called magnetars. See Feb. 2003 Scientific American for a great article on magnetars

For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. This finding was observed by ESO's X-shooter Identifying and Troubleshooting Neutron Namespaces Damian Igbe - November 21, 2013 - I recently gave you an intro to my talk at the Hong Kong OpenStack Summit about Neutron namespaces. Astronomers discover a massive neutron star that almost shouldn't exist. A superdense pulsar sits right on the line between normal and the weirdest objects in the universe. Studying neutron stars might help us figure out the origin of the heavy chemical elements, including gold and platinum, in our universe.

Identifying neutron star

What’s left after two neutron stars merge?

Astronomers recently detected the most massive neutron star to date, so massive that it approaches the theoretical limit for such stars. Despite it's mass, the neutron star is only 30 km in diameter.

(Black holes are technically denser, but far from normal.) Just a single sugar-cube worth of neutron-star material would weigh 100 million tons here on Earth, or about the same as the entire human population. A neutron star is composed almost entirely of neutrons, so let's first take a look at what a neutron is.

It is believed that under the immense pressures of a #eldddir #eldddir_space #eldddir_disaster A hypermassive neutron star was believed to have formed initially, as evidenced by the large amount of ejecta (much of which would have been swallowed by an immediately forming black hole). The lack of evidence for emissions being powered by neutron star spin-down, which would occur for longer-surviving neutron stars, suggest it collapsed into a black hole within milliseconds.

Angular momentum is conserved during a collapse, so the spin rate increases. Spin period is proportional to (radius) 2 To date, several accurate mass determinations of neutron stars are available from radio binary pulsars (Thorsett & Chakrabarty 1998), and they all lie in a narrow range (1.25¨ 1.44 One neutron star in an X-ray binary, Cyg X-2,M _). has an estimated mass of 1.8^0.2 (Orosz & KuulkersM 1999), but this determination is not as clean as for a radio_ binary. 2011-11-02 · Knowing the positions, proper motions, and distances of dozens of young nearby neutron stars, we can determine their past flight paths and possible kinematic origin.

Once the core of the star has completely burned to iron, energy production stops and the core rapidly collapses, squeezing electrons and protons together to form neutrons and neutrinos. If it is less than three solar masses it remains as a neutron star but if the star’s weight is more than about three solar masses, then it collapses further to form a black hole. Neutron stars and black holes should be coloured grey.

“There’s great interest in understanding how these interactions — a form of the strong force — are different between ordinary nucleons and strange nucleons containing up, down, and strange quarks,” Chen said.
