Anomalous flows in a sunspot penumbra
Rohan E. Louis, Christian Beck, Shibu K. Mathew +1
High-resolution spectropolarimetric observations of active region NOAA 11271 were obtained with the spectro-polarimeter on board Hinode to analyze the properties of an anomalous fl…
Small-scale chromospheric jets above a sunspot light bridge
Rohan E. Louis, Christian Beck, Kiyoshi Ichimoto
High-resolution broadband filtergrams of active region NOAA 11271 in Ca ii H and G band were obtained with the Solar Optical Telescope on board Hinode to identify the physical driv…
A three-dimensional view of the thermal structure in a super-penumbral canopy
C. Beck, D. Prasad Choudhary, R. Rezaei
We investigate the thermal topology in a super-penumbral canopy by determining the 3D thermal structure of an active region. We derive the temperature stratifications in the active…
Near-infrared spectropolarimetry of a delta-spot
H. Balthasar, C. Beck, R. E. Louis +2
Sunspots harboring umbrae of both magnetic polarities within a common penumbra (delta-spots) are often but not always related to flares. We present first near-infrared (NIR) observ…
