A new study by DTU Space researchers has revealed a neutron star that rotates around its axis at an extremely high speed. It spins 716 times per second, making it one of the fastest-spinning objects ever observed.
It is a small but extremely massive and fast-spinning object—a neutron star, part of a so-called X-ray binary star system called 4U 1820-30. It's found in the Sagittarius constellation toward the center of our galaxy.
"We were studying thermonuclear explosions from this system and then found remarkable oscillations, suggesting a neutron star spinning around its center axis at an astounding 716 times per second," says senior scientist Dr. Gaurava K. Jaisawal from DTU Space at The technical University of Denmark, who is part of an international team of researchers behind the new finding and first author on the article just published in The Astrophysical Journal.
"If future observations confirm this, the 4U 1820-30 neutron star would be one of the fastest-spinning objects ever observed in the universe, matched only by another neutron star called PSR J1748–2446."
