The role of ambipolar heating in the energy balance of solar prominences
Llorenç Melis, Roberto Soler
Solar prominence threads are typically located around magnetic dips, where cold and dense plasma is suspended against gravity in the hot corona thanks to the upward magnetic force.…
Alfvén wave propagation in the partially ionized lower solar atmosphere: a test of the single-fluid approximation
Roberto Soler
Alfvén waves are widely believed to play an important role in the transport of energy from the solar photosphere to the corona through the partially ionized chromosphere. In previ…
Wave coupling in partially ionized plasmas with shear flows I. Fast-to-Alfvén transformation
Miquel Cantallops, Roberto Soler
We theoretically investigate the interplay between magnetohydrodynamic (MHD) waves and shear flows in a partially ionized solar plasma, focusing on the energy exchange mediated by…
Linear analysis of shear-flow instabilities in a prominence-corona interface with ambipolar diffusion
Llorenç Melis, Roberto Soler
Observations have shown the presence of the Kelvin-Helmholtz instability (KHi) in solar prominences. Effects due to partial ionization of the prominence plasma may influence the KH…
