Amaris McCarver, an intern at the U.S. Naval Research Laboratory’s (NRL) Remote Sensing Division, and a team of astronomers have discovered a rapidly spinning neutron star that is beaming radiation across the universe like a cosmic lighthouse. The rapidly spinning neutron star, or “pulsar,” is located in the dense star cluster Glimpse-CO1, which lies in … Read more
Neutron stars are among the densest objects in the universe. The material inside them is so tightly compressed that scientists don’t yet know what shape it takes. The core of a neutron star may be a thick soup of quarks, or it may contain exotic particles that could not survive anywhere else in the universe. … Read more
Researchers have linked the periodic pulses of neutron stars to internal disturbances influenced by superfluid vortices. A new model suggests that these disturbances follow a power-law pattern observed in several natural phenomena. Credit: SciTechDaily.com A recent study has revealed the origin of the mysterious “heartbeats” observed in neutron stars, linking them to disturbances caused by … Read more
During the collision of binary neutron stars, hot neutrinos can become briefly stuck at the interface, leaving them out of equilibrium with the cold cores of the merging stars for 2 to 3 milliseconds. This interaction helps drive the particles toward equilibrium and provides new insights into the physics of such mergers. Credit: SciTechDaily.com New … Read more
Astronomers have detected a peculiar radio signal originating from deep space that eludes current scientific knowledge. The signal, designated ASKAP J1935+2148, repeats every 53.8 minutes, making it the longest period ever recorded for such a phenomenon. Published in the magazine Nature AstronomyThe discovery, made using the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope, has … Read more
