Fascinating how they've constrained the likelihood of AR Sco being a white dwarf instead of a neutron star. In terms of AR Sco's radio properties, nothing else quite like it has been found. Could be intermediate polars (IPs) – "which feature spinning magnetic white dwarfs accreting from low-mass stars in close binaries." The paper can be found in the eso.org public archives: A radio pulsing white dwarf binary star
