Time series of high resolution photospheric spectra in a quiet region of the Sun. II. Analysis of the variation of physical quantities of granular structures
K. G. Puschmann, B. Ruiz Cobo, M. Vazquez +2
From the inversion of a time series of high resolution slit spectrograms obtained from the quiet sun, the spatial and temporal distribution of the thermodynamical quantities and th…
Time series of high resolution photospheric spectra in a quiet region of the Sun. I. Analysis of global and spatial variations of line parameters
K. G. Puschmann, M. Vazquez, J. A. Bonet +2
A 50 min time series of one-dimensional slit-spectrograms, taken in quiet sun at disk center, observed at the German Vacuum Tower Telescope (Observatorio del Teide), was used to st…
The GREGOR Fabry-Perot Interferometer - A New Instrument for High-Resolution Spectropolarimetric Solar Observations
Klaus G. Puschmann, Horst Balthasar, Svend-Marian Bauer +6
Fabry-Perot interferometers have advantages over slit spectrographs because they allow fast narrow-band imaging and post-factum image reconstruction of spectropolarimetric data. Te…
Supersonic Evershed flow outside Sunspots
V. Martinez Pillet, Y. Katsukawa, K. G. Puschmann +1
We report on the discovery of mostly horizontal field channels just outside sunspot penumbrae (in the so-called `moat' region) that are seen to sustain supersonic flows (line-of-si…
