Spectral signatures of bright grains determine chromospheric heating
Elias R. Udnæs, Tiago M. D. Pereira
Chromospheric heating is an important ingredient in the energy budget of the solar atmosphere, which is challenging to quantify from observations. By using 3D radiative magnetohydr…

Solar Vortices as Conduits for Magnetoacoustic Waves: Multi-Layer Coupling and Their Role in Atmospheric Heating
Suzana S. A. Silva, Ioannis Dakanalis, Luiz A. C. A. Schiavo +10
The Sun's atmosphere hosts swirling plasma structures, known as solar vortices, which have long been thought to channel wave energy into higher layers. Until now, no direct observa…

Characteristics of acoustic-wave heating in simulations of the quiet Sun chromosphere
Elias R. Udnæs, Tiago M. D. Pereira
Understanding energy transfer through the chromosphere is paramount to solving the coronal heating problem. We investigated the energy dissipation of acoustic waves in the chromosp…
