The Bright Rim Prominences according to 2.5D Radiative Transfer

The Astrophysical Journal Letters
Solar prominences observed close to the limb commonly include a bright feature that, from the perspective of the observer, runs along the interface between itself and the underlying chromosphere. Despite several idealized models being proposed to explain

Observations of the Formation and Disappearance of a Funnel Prominence

The Astrophysical Journal Letters
We present an observational study of the formation and disappearance of a funnel prominence. Before the funnel prominence formed, cool materials from the top of a preexisting polar crown prominence flowed along saddle-shaped coronal loops to their base ...

Magnetic Field Stratification in Active-region Plage from Ca ii K and Ca ii 8542 Å Spectropolarimetry

The Astrophysical Journal Letters
We investigate the height variation of the line-of-sight (LOS) magnetic field in solar active-region (AR) plage from the upper photosphere to the upper chromosphere using cospatial ultraviolet and infrared spectropolarimetric observations from the ...

Magnetic Fields beneath Active Region Coronal Loops

The Astrophysical Journal
We examine the hypothesis that multipolar magnetic fields advected by photospheric granules can contribute to heating the active chromosphere and corona.

Constraints on Acoustic Wave Energy Fluxes and Radiative Losses in the Solar Chromosphere from Non-LTE Inversions

The Astrophysical Journal
Accurately assessing the balance between acoustic wave energy fluxes and radiative losses is critical for understanding how the solar chromosphere is thermally regulated.
