A quartet of researchers at IRAP, Université de Toulouse, has found a way to measure the interior magnetic field of red giant stars. In their paper published in the journal Nature, Gang Li, Sébastien Deheuvels, Jérôme Ballot and François Lignières describe how they used data from the Kepler satellite to calculate the interior magnetic field strength for red giants. Lisa Bugnet, with the Flatiron Institute, in New York has published a News & Views piece in the same journal issue outlining the difficulties in measuring magnetism in stars and the work done by the team in France.
