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…
Measuring the ionisation fraction in a jet from a massive protostar
Sanna, A.; Purser, S. J. D.; Ray, T. P. +7 more
It is important to determine if massive stars form via disc accretion, like their low-mass counterparts. Theory and observation indicate that protostellar jets are a natural consequence of accretion discs and are likely to be crucial for removing angular momentum during the collapse. However, massive protostars are typically rarer, more distant an…
