white dwarf

Badenes's team examined archival observations and found a white dwarf and neutron star orbiting one another extremely closely.

An astronomer makes the case that the best place to search for habitable planets may be very close to white dwarf stars.

A white dwarf is a "dead" star that doesn't generate its own energy like the sun does, Provencal says.

The center of that star then transformed into a white dwarf , at once very hot (more than 100, 000 Kelvin) and very small.

It's about as massive as Jupiter, but much more compact. It may be the remains of a carbon-rich white dwarf star.

otherwise, it will simply contract until electron degeneracy pressure halts its collapse, thus directly turning into a white dwarf.

A white dwarf is the inert remnant of what used to be a sunlike star.

Part of a binary star system, the compact white dwarf gradually captured material from its companion star.

In the former case, material is stripped from the binary partner until the material reaches "critical mass" around the white dwarf.

As the main-sequence mass of the star increases, the mass of the final remnant left as a white-dwarf star also increases.

So the ultimate fate of our own watery planet may be to briefly stain the atmosphere of the white-dwarf sun.

The observations also show for the first time that a white dwarf can create a cavity around it before blowing up in a Type Ia event.

In 1915 astronomers at the Mount Wilson Observatory determined that Sirius B was a white dwarf star , the first to be discovered.

The exploding white dwarf star is currently brightening in the Pinwheel Galaxy, nestled, from our perspective, within the Big Dipper.

The central planetary nebula nucleus (PNN) or white dwarf central star is the fainter of these two stars.

Since a 7-solar-mass is too large to be a white dwarf or neutron star, it must be a black hole.

Recall that Type I supernova is the strong explosion of a nova that even the white dwarf is destroyed.

Some day, millions of years from now, LS IV-14 116 will cool off to the point where it becomes a bona fide white dwarf.

It may be the remains of a carbon-rich white dwarf star.

The nova phenomenon generally occurs in a binary system that has as one member a very hot white dwarf .

Than it shrink down to a skeleton of its former self-- a white dwarf.

If the star is small, it collapses gently and remains collapsed. This is called white dwarf.

An open question remains whether these white dwarf mergers are the primary catalyst for Type 1a supernovae in spiral galaxies.

Cataclysmic variables involve gas falling from a large star onto an accretion disk surrounding a massive but compact white dwarf star.

"A white dwarf is like a smoking cinder from a burnt-out fire, " Williams said.

Our sun should become a white dwarf in about five billion years. The process will destroy Mercury, Venus and possibly Earth.

As the white dwarf spins, the columns of infalling gas rotate with it.

Except for an anomalously high surface abundance of nitrogen, the white dwarf should appear unchanged.

The primary target is a white dwarf star known as GD358 in the constellation Hercules.

Sagala could be an equivalent to the degenerate and super dense matter of white dwarf stars.

His team used observations from NASA's Spitzer space telescope to investigate dead white dwarf stars.

But that's exactly right. Our sun is expected to end its life as a White Dwarf.

New material from the frantically orbiting white dwarf would quickly replenish the blown- apart disk, Strohmayer says.

A white dwarf star pulsates or quakes as waves of energy travel through it.

The hot, remnant stellar core of NGC 2818 will eventually cool off for billions of years as a white dwarf.

A two-wheeled cart went rumbling past them, pulled by a white dwarf elephant.

It will quietly and steadily burn the hydrogen to helium and become a white dwarf.

It orbits the "white dwarf" core of a star .

This implies that white dwarf mergers dominate in these galaxies.

Picture on the left shows the white dwarf, and one on the right shows the supernova.

When a white dwarf takes on enough mass in this manner it reaches a level called the chandrasekhar limit.

A planetlike body 4, 000 light-years away may be the compacted remains of a white dwarf star that is now mostly diamond.

The record-breaking star is 63 million light years from Earth and orbits a dense, collapsed "white dwarf" star.

I've found that these three questions can help determine whether a secret is a white dwarf or a black hole.

The binary system of a giant star and hot white dwarf star orbit each other about once every 120 years.

Volantis was overrun with white dwarf elephants.

If a star is small, it collapses and remains collapsed, this is called a White Dwarf.

A white dwarf retains about half of its mass but becomes incredibly dense because of its small size.

The star, which was similar to our sun, had died peacefully and turned into a dense white dwarf.

Our sun is ^ end its life as a white dwarf.

The star was a white dwarf called GD 362, and it's 150 light years from Earth, still within our galaxy.

The picture on the left shows a white dwarf, and on the right shows a supernova.

It is also a circumbinary planet, orbiting around a binary system composed of the pulsar PSR B1620-26 A and the white dwarf WD B1620-26.

The collapse of a star may produce a White Dwarf or a neutron star
