Kind: research · Impact: medium

## In brief

- Researchers linked long-period radio transient pulses to a white dwarf orbiting a Sun-like star.
- The pulses arrive roughly every eight minutes, per the sources.
- The system is described as the first known of its kind, located about 5,000 light-years away.

## Why it matters

The discovery identifies a new class of radio transient and points to binary interactions and magnetic activity as possible drivers, which bears on how such sources are classified and studied.
