"The data taken at the W. M. Keck Observatory provided firm evidence that this system had a strong magnetic field and was funneling matter onto the white dwarf," Rodriguez says.
Now we have discovered that the star's magnetic field plays a key role in this process, resulting in a scar on the white dwarf's surface," study lead author Stefano Bagnulo, an astronomer at ...
Scientists have discovered two rare white dwarfs—which are among the dimmest stars in the universe—that feature changes in their surface composition caused by magnetic fields.
About 20% of white dwarfs possess a strong magnetic field. Some white dwarfs, like this one, have both traits - they have an atmosphere polluted by metal elements and are permeated by a magnetic ...
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.
Why do some white dwarfs have a magnetic field while others don’t? A new research project aims to understand this mystery of the universe.
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.
Gif: K. Miller, Caltech/IPAC The researchers believe that the dwarf’s two-facedness may be due to its intense magnetic fields.
The future of yellow dwarf stars, like our sun, is determined almost entirely by their mass. The most massive stars, about eight to 12 times heftier than the sun, can explode as supernovae ...
