Ghostly Hosts: Looking for the Sources of Enrichment
What created the strong CIV absorption near this Lyman Alpha Emitter?
On the Insides of Giants: Heat Transfer in Hot-Start, Core-Accreting Gas Giants
Thick clouds shroud the interiors of gas giants, like Jupiter, in mystery. Today’s authors set out to blow some of that mystery away. Using equations and modeling, they explore processes of heat transfer within the interiors of hot-start, core-accreting gas giants.
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.

Astrophysical Classics: The Lost Art of Fishing in a Black Hole
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.
The Measure of Things
200 years ago, Joseph Fourier had an idea that added a whole new dimension to physics.
How well do we measure the radii of white dwarfs?
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?
