Kind: research · Impact: medium

## In brief

- A new type of long-period radio transient has been discovered.
- The system consists of a white dwarf and a Sun-like star.
- The finding raises questions about the role of binary interactions and magnetism in such objects.

## Why it matters

It identifies a new class of long-period radio transient in a binary system, which may help constrain how white dwarfs and companion stars interact and generate magnetic radio emission.
