ASTRON’s LOFAR low-frequency array radio telescope identified the magnetic field of the ‘brown dwarf’
Translated by J Bank
Researchers from ASTRON, the Dutch institute for radio astronomy in Dwingeloo in the province Drenthe, have become the first to observe a ‘brown dwarf’ using a radio telescope, reports RTV Drenthe.
Brown dwarfs are sometimes called ‘failed’ stars. They are spheres of gas that are larger than the gas-giant planets (such as Jupiter or Saturn), but too small to develop the temperature and pressure necessary for nuclear fusion and development into a star. Scoop
Normally, brown dwarfs are detected using infrared telescopes, because they emit more radiation in the infrared spectrum. But now the LOFAR low-frequency array telescope has been used by researchers to ‘see’ the brown dwarf thanks to its magnetic field.
