"It looks like brown dwarfs are the missing step between the radio emissions we see generated at Jupiter and those we observe from pulsars".
From the article:
"A class of "failed" star called a brown dwarf emits beams of radiation that are thousands of times brighter than any released by the Sun.
The brown dwarfs are behaving like an altogether different and exotic cosmic object called a pulsar."
Brown dwarfs are stellar also-rans which lack the necessary mass to kick-start nuclear fusion reactions in their cores.
Greg Hallinan from the National University of Ireland in Galway and his colleagues used the Very Large Array radio telescope in New Mexico to observe a very cool, rapidly rotating brown dwarf called TVLM 513-46546."
A bright flash from the brown dwarf was observed roughly every two hours, and are very similar to those observed from pulsars. But this whole system is on a much slower and smaller scale, so it is easier for astronomers to decipher what is going on.
For some time, scientists have wondered if there were similarities between this type of emission and the periodic radio beams from pulsars. Observations of TVLM 513-46546 could provide the first direct evidence for such a link.
