Radio emissions from terrestrial planets around white dwarfs

Terrestrial planets in close orbits around magnetic white dwarf stars are potential electron-cyclotron maser sources, by analogy to planetary radio emissions generated from the electrodynamic interaction between Jupiter and the Galilean moons. We present predictions of radio flux densities and the n...

Description
Summary:Terrestrial planets in close orbits around magnetic white dwarf stars are potential electron-cyclotron maser sources, by analogy to planetary radio emissions generated from the electrodynamic interaction between Jupiter and the Galilean moons. We present predictions of radio flux densities and the number of detectable white-dwarf/terrestrial-planet systems, and discuss a scenario for their formation.
