Pebbly Planets
According to one theory of planet formation, the secret to forming massive planets is through itsy-bitsy, teeny-weeny pebbles of dust. In today’s astrobite, we explore what sort of planets these little pebbles could form.
Yoga for dark matter: Making the Cold Dark Matter model more flexible
… and therefore more powerful. Describing dark matter as a fluid allows us to model dark matter candidates with great accuracy.
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.
