Memories of a (former) astrobiter
We learn a lot of things writing for Astrobites. In this post, I talk about a few of my experiences.
How many stars have companions?
The fraction of binary stars has implications in many fields of astronomy. Yet, we still don’t know this number, and even less how it varies with properties such as metallicity. Today’s paper sheds some light on this open question.

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.

40 Eridani B: a Challenging Star
40 Eridani B was the first white dwarf to be discovered, but details of its structure and composition remained a mystery, until today’s paper.
New twinkles in the sky
Pulsations are the way for astronomers to probe the interior of stars. Today’s paper announces the discovery of a new class of pulsator stars. What makes them different? And what exciting new things can we learn from that?
