...the term "Magnetospheric radio emissions [Exoplanets]" [..] is presented as a narrower term than "Gravitational microlensing [Exoplanets]". I can't really understand on what ground that link was made. My suggestion would be that there is a "Magnetospheric radio emissions" (outside the exoplanet context), as those radio emissions are observed and studied since the 50's... while exoplanetary radio emissions have not been detected yet.
To me they [magnetospheric radio emissions and gravitational microlensing] are both possible detection methods for exoplanets, but there is no apparent hierarchical link between them.
