Long-period transients are repeating radio pulses of mysterious origin with minute-to-hour periods. The longest-lived of these — GPM J1839–10 — is now shown to be a binary system and seemingly mirrors the more rapid white dwarf pulsars, in which interaction of a stellar remnant with a companion star generates powerful radio beams.
