The coolest radio-wavelength-producing star examined in this study, astronomers at the University of Sydney have shown the recently discovered, faint star to be a glob of gas burning at regarding 425 degrees Celsius. The surface temperature of the Sun, a nuclear hell, is regarding 5,600 degrees. And while it’s not the coolest star ever found, it is the coolest in terms of its potential to emit radio waves. The results were published in The Astrophysical Journal Letters. According to Phys, “It is very rare to find supercool brown dwarf stars like this one that produce radio emissions.” This is because their dynamics do not usually generate the magnetic fields that generate radio emissions detectable from Earth. “Finding this star that produces radio waves at such a low temperature is an amazing discovery,” he added. In this case, the radio waves are thought to be generated by a stream of electrons in the star’s magnetic pole region, which produce regularly repeated radio bursts. Rose analyzed the star using new data from the CSIRO ASKAP telescope in Western Australia and observations from the Australian Integrated Telescope Array near Narrabri in New South Wales and the Meerkat telescope in South Africa.
