Energy transport in white dwarfs: what about magnetic fields?
Magnetic fields always make things more compiclated. In today’s paper, the authors studied their effect on the atmosphere of white dwarf stars.

In a strange, half-lost, piece of work Roger Penrose draws four figures dropping their lines into the depths of a black hole, and in doing so finds a new and hugely influential way to steal energy away from the heart of a spinning singularity.
200 years ago, Joseph Fourier had an idea that added a whole new dimension to physics.
The accuracy of our estimates of the radii of white dwarf stars has important implications to cosmology. We currently rely on a theoretical mass-radius relationship for that. Are we doing a good job?

In this series of posts, we sit down with a few of the keynote speakers of the 230th AAS meeting to learn more about them and their research.
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
