Hypervelocity stars (HVS) are celestial bodies moving at speeds sufficient to escape the Milky Way's gravitational pull, with a primary proposed origin involving binary star interactions with the ...

The bright binary star system V Sagittae will flare up multiple times before finally going supernova within the next 100 years. When it explodes, it could be visible to the naked eye even in sunlit ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of millions of years, these stars progressively cool down, radiating heat into ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

This illustration shows the double star V Sagittae. It’s about 10,000 light-years from Earth, and hosts a Wolf-Rayet star that’s drawing material away from its main sequence companion. Credit: ...

A teaspoon that weighs a billion tons? Welcome to the world of neutron stars the ultra-dense cores left after colossal supernovae. In this video, we break down how these objects form (from the iron ...

Neutron stars are the remnants of dead stars after their explosion, much like that of white dwarf stars, but they are spawned from much more massive stars. These supernovae are greatly intensified and ...

New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...

Astronomers find an explanation for the fastest stars in the galaxy while uncovering a new mechanism for a supernova explosion. Credit: Technion illustration Astronomers call a special kind of ...

(THE CONVERSATION) The Sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the Sun ...
