A research team has investigated long-term X-ray variability in the neutron star NGC 7793 P13, an object thought to be driven ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...

Astronomers tracked a decade of dramatic changes in P13, a neutron star undergoing supercritical accretion. Its X-ray ...

Neutron stars are what remain after giant stars collapse, leaving behind a body so dense that its core crushes protons and neutrons into a tightly packed soup. These objects cool very slowly over ...

When gas falls onto a compact object, such as a neutron star or black hole, due to its strong gravity (a process called accretion), it emits ...

In the end, the Universe becomes a place where gravity and quantum physics slowly turn all mass into faint streams of particles.

Neutron stars—the dense remnants of massive stellar explosions—and their presence in X‐ray binaries serve as natural laboratories for extreme physics. In these systems, matter is transferred from a ...

A spoonful of this star's matter can weigh a billion tons. By developing a new theoretical relation describing just how compact neutron stars — which are the remnants of massive stars that have gone ...

"What is remarkable is that the time between pulse pairs seems to follow a choreographed pattern." Using the world's most advanced radio telescopes, astronomers have discovered a spinning dead star so ...

A rapidly spinning neutron star orbits a smaller, helium-rich star very closely. This unique pair formed when a larger star exploded, leaving behind the neutron star which then interacted with its ...

It weighs more than 2 times the mass of our sun, but is only 18 miles wide. Astronomers have discovered the "most massive neutron star ever measured," amassing to more than two times the mass of our ...
