Astronomers at the University of Sydney have shown that the recently discovered, dim little star is the coldest ever to produce an emission along the radio wave, and examined in the study, which is a ball of gas that boils at about 425 degrees Celsius. The surface temperature of the sun, a nuclear hell, is about 5,600 degrees.
Although it’s not the coldest 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’s very rare to find supercool brown dwarf stars like this one that produce radio emission,” said Coffey Rose, a researcher in the School of Physics. This is because their dynamics do not typically produce 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 produced by a flow of electrons into the star’s magnetic pole region, which produces regularly repeating radio bursts.
Rose analyzed the star using new data from the CSIRO ASKAP telescope in Western Australia and follow-up with observations from the Australia Integrated Telescope Array near Narrabri in New South Wales and the Meerkat telescope in South Africa.
