A neutron star is the remnant of a massive star that has run out of fuel, exploded, and collapsed into a superdense star. Like a white dwarf, a neutron star will cool over about 10 10 years to a ...

But if GRB211211A was caused by a neutron star merging with a white dwarf in an unusual way, “then we don’t expect we will see any detectable gravitational event.” ...

More Astronomers have discovered the "missing link" connecting the death of sunlike stars to the birth of white dwarf stellar remnants, in the form of a "teenage vampire" white dwarf. This vampire ...

This white dwarf started its life as a star about twice the sun's mass, living a lifespan of perhaps 1.2 billion years before entering its death throes.

Recommended Videos Only two other types of objects – black holes and neutron stars – are more compact than white dwarfs. The way this white dwarf, named ZTF J1901+1458, was born also is unusual.

The remaining core is about the size of Earth, but with 200,000 times its mass. The red dwarf, in contrast, is a large, cool star with about a third the mass of our sun.

Rather than a single flashing star, the signals were traced to a binary system located 1,600 light-years away. It consists of a white dwarf, the remnant of a dead star, and a red dwarf, a much ...

A distant star has a dead star companion lurking in its vicinity that could be a monster-massive white dwarf, raising the question: how has it avoided being devoured by this cosmic zombie?

A white dwarf comes into being when a star whose mass is not big enough to become a black hole or neutron star reaches the point at which it runs out of fuel. Looking at this white dwarf is like ...

NASA's Hubble Space Telescope has for the first time observed a cluster of white dwarfs — the tiny, super-dense remains of burned-out stars — at the centre of the Milky Way.

White dwarf stars represent the evolutionary endpoints of medium- and low-mass stars, comprising the dense, electron-degenerate cores left after nuclear fuel exhaustion. In binary systems ...
