Magnetic A and B stars can emit periodic radio pulses through electron cyclotron maser emission (ECME), but identifying these stars has been biased by previous methods. This study uses a new strategy focusing on variability in total intensity, discovering new candidates and confirming three as Main-sequence Radio Pulse emitters (MRPs).

Why it matters: New detection approach reduces bias, expanding the sample of MRPs and improving understanding of ECME mechanisms.

The big picture: ECME luminosity in magnetic A and late-B stars depends on temperature and magnetic field strength, but their effects intertwine.

The stakes: Limited sample size and parameter degeneracy hamper clear insights into rotation's influence on ECME and radio emission.

Quick takeaway: Variability-based detection without polarisation data effectively identifies MRPs, enhancing future all-sky survey strategies.
