Well, it was a small white dwarf star.
Thus the white dwarf Sun will gradually cool, growing dimmer and dimmer.
This type of star is called a“white dwarf.”.
With extremely dense mass. a white dwarf-- or a partially burnt-out star.
With no active fusion, the core collapsed into a white dwarf.
On the surface of the white dwarf, the accreted gas will become compressed and heated.
Is gonna happen to earth. What happened here around this white dwarf.
During their trek hits Nelio a white dwarf named Yabu Bata.
The degenerate helium core will keep on contracting, andfinally becomes a helium white dwarf.
Eventually, such a star will become a so-called white dwarf, a highly condensed sphere.
At this point it will pass through a red giant stage, then settle down to become a white dwarf.
Put simply, a nearby white dwarf might appear to be brighter than a distant red Super Giant.
The vast majority of these are found orbiting ancient white dwarf companion stars.
Animation showing the white dwarf star Stein 2051B as it passes in front of a distant background star.
It is also seen in astrophysical measurements, notably for light escaping the white dwarf Sirius B.
The electron-degenerate matter inside a white dwarf is no longer a plasma, even though stars are generally referred to as being spheres of plasma.
Shortly thereafter, the star's supply of hydrogen will be completely exhausted and it will become a helium white dwarf.
The explosion is created when the white dwarf accretes hydrogen from the companion star, building up mass until the hydrogen undergoes fusion.
Someday, when Sirius runs out of fuel and becomes a red giant, it will shed its substance onto the white dwarf.
Its companion(IK Pegasi B) is a massive white dwarf- a star that has evolved past the main sequence and is no longer generating energy through nuclear fusion.
For a core primarily composed of oxygen, neon and magnesium, the collapsing white dwarf is likely to form a neutron star.
A binary star system that includes a nearby white dwarf can produce certain types of these spectacular stellar explosions, including the nova and a Type 1a supernova.
An example of such a star system is RS Ophiuchi, a binary system consisting of a red giant and a white dwarf companion.
If the red giant doesn't have enough mass, it will simply collapse into a white dwarf and spend a couple billion years slowly dimming as it gives off its stored energy.
The binary system as a whole has some similarities to thenearby system of Sirius, which has a class-A primary and a white dwarf companion.
An alternate model that allows the white dwarf to steadily accumulate mass without erupting as a nova is called the close-binary supersoft x-ray source(CBSS).
How can old objects exist in nearby space, such as the white dwarf(WD) star orbiting Sirius?
Image above: This is an artist's impression of a rocky and water-rich asteroid being torn apart by the strong gravity of the white dwarf star GD 61.
This would result in a(recurrent) nova explosion- a cataclysmic variable star- and the luminosity of the white dwarf would rapidly increase by several magnitudes for a period of several days or months.
In a new study, researchers from the Max Planck Institute for Gravitational Physics(Albert Einstein Institute/AEI) in Potsdam and from the French Alternative Energies andAtomic Energy Commission(CEA) in Saclay, Paris propose detecting exoplanets orbiting ancient white dwarf binaries in the Milky Way.
