Chromospheric and coronal heating in an active region plage by dissipation of currents from braiding

De Pontieu, Bart; Hansteen, Viggo; Sainz Dalda, Alberto +3 more

The question of what heats the outer solar atmosphere remains one of the longstanding mysteries in astrophysics. Statistical studies of Sun-like stars reveal a correlation between global chromospheric and coronal emissions, constraining theoretical models of potential heating mechanisms. However, spatially resolved observations of the Sun have sur…
