摘要
RX J0648.0-4418is a compact star with a spin period of 13.2 s. It is either the most rapidly rotating white dwarf known or a slowly rotating neutron star. Here, we report on the first searches for coherent pulsar-like radio emission from RX J0648.0-4418, both for sporadic bursts and steady periodic emission. No such emission was detected, with our limits suggesting that no such mechanism is active. We further searched our data for fast radio bursts to a dispersion measure corresponding to a redshift of similar to 12. We did not detect any such events.
