Heating of the solar chromosphere in a sunspot light bridge by electric currents
Rohan E. Louis, Avijeet Prasad, Christian Beck +2
Context: Resistive Ohmic dissipation has been suggested as a mechanism for heating the solar chromosphere, but few studies have established this association. Aim: We aim to determi…
The formation of an atypical sunspot light bridge as a result of large-scale flux emergence
Rohan E. Louis, Christian Beck, Debi P. Choudhary
We use a combination of full-disk data from the Solar Dynamics Observatory and high-resolution data from the Dunn Solar Telescope (DST) to study the formation, structure, and evolu…
Center-to-Limb Variation of the Inverse Evershed Flow
C. Beck, D. P. Choudhary, M. Ranganathan
We present the properties of the inverse Evershed flow (IEF) based on the center-to-limb variation of the plasma speed and loop geometry of chromospheric superpenumbral fibrils in…
Temporal Evolution of the Inverse Evershed Flow
C. Beck, D. P. Choudhary
The inverse Evershed flow (IEF) is an inflow of material into the penumbra of sunspots in the solar chromosphere that occurs along dark, elongated superpenumbral fibrils extending…
Magnetic Properties and Flow Angle of the Inverse Evershed Flow at Its Downflow Points
C. Beck, D. P. Choudhary
We determined the direction and strength of the photospheric and lower chromospheric magnetic field in the umbra and penumbra of a sunspot from inversions of spectropolarimetric ob…
Evolution of Photospheric Vector Magnetic Field Associated with Moving Flare Ribbons As Seen By GST
Chang Liu, Wenda Cao, Jongchul Chae +7
The photospheric response to solar flares, also known as coronal back reaction, is often observed as sudden flare-induced changes in vector magnetic field and sunspot motions. Howe…
