Astronomers<\/a> in their recent discovery have observed a neutron star spinning at an astonishing 716 rotations per second, making it one of the fastest-spinning stars ever recorded. This neutron star, found in the binary system 4U 1820-30 within the globular cluster NGC 6624, is situated around 26,000 light-years away from Earth in the constellation of Sagittarius. Observed through NASA’s<\/a> Neutron star Interior Composition Explorer (NICER<\/a>) aboard the International Space Station (ISS<\/a>), the star’s surface also emits explosive thermonuclear blasts akin to atomic detonations.<\/p>\n

Discovery and Observations<\/h2>\n

Scientists from DTU Space, using data collected between 2017 and 2021, detected 15 thermonuclear bursts on the star’s surface, with one carrying a distinct signature indicating<\/a> burst oscillations at 716 Hz. This confirmed the star’s spin rate, matching that of another fast-spinning neutron star, PSR J1748\u20132446. “During these bursts, the neutron star becomes up to 100,000 times brighter than sun, releasing immense energy,\u201d noted Jerome Chenevez of DTU Space.<\/p>\n

Extreme Properties of Neutron Stars<\/h2>\n

Neutron stars, remnants of massive stars that have exhausted their nuclear fuel, are known for their extreme densities and rapid spins. When a star collapses in a supernova, its core condenses to about 20 kilometres in diameter but retains a mass up to twice that of our sun. This rapid collapse causes it to spin at incredible speeds, a phenomenon explained by angular momentum conservation. Additionally, in binary systems like 4U 1820-30, neutron stars often draw in matter from companion stars, further accelerating their rotation.<\/p>\n

A New Insight into Binary Star Systems<\/h2>\n

The 4U 1820-30 system includes a white dwarf orbiting the neutron star at a rate of once every 11 minutes, the shortest known orbital period for a binary star system. This rapid orbit contributes to frequent matter transfers, creating conditions for explosive thermonuclear reactions on the neutron star’s surface.<\/p>\n

These discoveries provide a unique view of the life cycle of neutron stars and the complex dynamics within binary systems.<\/p>\n
