Horizontal motions in sunspot penubrae
Michal Sobotka, Klaus G. Puschmann
High-resolution observations of horizontal motions in the penumbra are needed to complement the concept of penumbrae obtained from spectropolarimetry. Time series of intensity imag…
The polarization signature of photospheric magnetic fields in 3D MHD simulations and observations at disk center
C. Beck, D. Fabbian, R. Rezaei +1
Before using 3D MHD simulations of the solar photosphere in the determination of elemental abundances, one has to ensure that the correct amount of magnetic flux is present in the…
Spectroscopy at the solar limb: II. Are spicules heated to coronal temperatures ?
C. Beck, R. Rezaei, K. G. Puschmann +1
Spicules of the so-called type II were suggested to be relevant for coronal heating because of their ubiquity on the solar surface and their eventual extension into the corona. We…
The GREGOR Fabry Perot Interferometer (GFPI), Technical Innovations and Results achieved in 2013
Klaus Gerhard Puschmann
This paper shall provide a summary of not yet published technical innovations to the GREGOR Fabry-Perot Interferometer (GFPI) at the 1.5m GREGOR Solar Telescope (Europe's largest s…
Spicules and their on-disk counterparts, the main driver for solar chromospheric heating?
Klaus Gerhard Puschmann
The question how the outer solar atmosphere is heated from solar photospheric temperatures of about 5800K up to solar chromospheric and coronal temperatures of about 20.000K and mi…
Sunspot splitting triggering an eruptive flare
Rohan E. Louis, Klaus G. Puschmann, Bernhard Kliem +2
We investigate how the splitting of the leading sunspot and associated flux emergence and cancellation in active region NOAA 11515 caused an eruptive M5.6 flare on 2012 July 2. Our…
