About 8,150 light-years from Earth, a white dwarf star named Gaia22ayj has intrigued astronomers. Its unusual behavior, ...

White dwarf with nearly pure oxygen atmosphere surprises astronomers “In my opinion, it means that the magnetic field might not be dipolar,” Tremblay says. “Instead it might be a quadrupole, with four ...

The peculiar double-faced nature of this white dwarf star might be due to the interplay of magnetic fields and convection, or a mixing of materials.

Astronomers have discovered a white dwarf star, or the burnt core of a dead star, that has two completely different faces. One is made of hydrogen, while the other is made of helium.

The magnetic fields in white dwarfs can be more than a million times stronger than the magnetic field of the Sun, and the dynamo model helps to explain why.

The magnetic fields in white dwarfs can be more than a million times stronger than the magnetic field of the Sun, and the dynamo model helps to explain why. The discovery of J1912−4410 provided ...

The magnetic fields in white dwarfs can be more than a million times stronger than the magnetic field of the Sun, and the dynamo model helps to explain why.

But the magnetic field can also play a part in more or less constraining the plasma around white dwarfs, creating different pressures and densities in their atmospheres.

Two theories for a two-faced star One theory is that Janus’s magnetic field is in some way lopsided or uneven, such that it is inhibiting the convection currents on one side of the white dwarf ...

Astronomers have spotted a white dwarf star with a patch of metal near one of its magnetic poles, which probably formed when the star devoured a small planet ...

Astronomers have discovered a "teenage vampire" dead star in the process of devouring a companion star during a short-lived, "missing link" phase of its evolution.
