Spectropolarimetry of a decaying sunspot penumbra
L. R. Bellot Rubio, A. Tritschler, V. Martinez Pillet
We report on high angular resolution, high precision spectropolarimetric measurements of a decaying sunspot. The spot gradually lost its penumbra during the course of three days. I…
The Fine-Structure of the Net-Circular Polarization in a Sunspot Penumbra
A. Tritschler, D. A. N. Mueller, R. Schlichenmaier +1
We present novel evidence for a fine structure observed in the net-circular polarization (NCP) of a sunspot penumbra based on spectropolarimetric measurements utilizing the Zeeman…
Flow Field Evolution of a Decaying Sunspot
Na Deng, Debi Prasad Choudhary, Alexandra Tritschler +3
We study the evolution of the flows and horizontal proper motions in and around a decaying follower sunspot based on time sequences of two-dimensional spectroscopic observations in…
Two-Dimensional Spectroscopy of Photospheric Shear Flows in a Small delta Spot
C. Denker, N. Deng, A. Tritschler +1
In recent high-resolution observations of complex active regions, long-lasting and well-defined regions of strong flows were identified in major flares and associated with bright k…
The discrepancy in G-band contrast: Where is the quiet Sun?
Han Uitenbroek, Alexandra Tritschler, Thomas Rimmele
We compare the rms contrast in observed speckle reconstructed G-band images with synthetic filtergrams computed from two magneto-hydrodynamic simulation snapshots. The observations…
