India, May 13 -- FRANCE - A study published in The Astrophysical Journal Letters by an international team* coordinated by Tahar Amari, CNRS research director at the Center for Theoretical Physics (CPHT**) at Ecole Polytechnique, shows that twisted flux ropes (TFRs) are omnipresent in the Sun, even in its quietest regions. Their work, combining high-resolution observations and advanced simulations, explains how those TFRs help to heat the solar atmosphere to extreme temperatures.

The study published in The Astrophysical Journal Letters by the team led by Tahar Amari, CNRS research director at Ecole Polytechnique's CPHT, is a new episode in the scientific series seeking to understand which magnetic structures provide the energy necessary f...
