Evidence of ubiquitous Alfvén pulses transporting energy from the photosphere to the upper chromosphere

Wang, Yuming; Liu, Jiajia; Erdélyi, Robert +2 more

The multi-million degree temperature increase from the middle to the upper solar atmosphere is one of the most fascinating puzzles in plasma-astrophysics. Although magnetic waves might transport enough energy from the photosphere to heat up the local chromosphere and corona, observationally validating their ubiquity has proved challenging. Here, w…
