Measuring the Expansion of Solar Magnetic Fields with Multiline Inversions from Sunrise III

Juan Carlos Trelles Arjona, María Jesús Martínez González, Christoph Kuckein +34

Magnetic fields in the solar atmosphere are expected to expand with height, forming magnetic canopies that couple the photosphere and chromosphere. Except for sunspots, direct meas…

Solar chromospheric heating by magnetohydrodynamic waves: dependence on magnetic field inclination

Mayu Koyama, Toshifumi Shimizu

A proposed mechanism for solar chromospheric heating is that magnetohydrodynamic waves propagate upward along magnetic field lines and dissipate their energy in the chromosphere. I…
