In the past three years, astronomers have discovered a mysterious new type of radio source called these long period transients.

These objects emit bright radio signals that repeat every few minutes to every few hours. The astronomers have found about a dozen examples, but we still don’t understand which type of star could emit radio pulses in this peculiar way. In the research ‘Sporadic radio pulses from a white dwarf binary at the orbital period‘, the astronomers have discovered a new long period transient. Furthermore, they identified the stars responsible for the mysterious radio flashes – a breakthrough never achieved before.
