Fast inversion of solar Ca II spectra
C. Beck, D. Prasad Choudhary, R. Rezaei +1
We present a fast (<< 1 s per profile) inversion code for solar Ca II lines. The code uses an archive of spectra that are synthesized prior to the inversion under the assumption of…
The magnetic configuration of a delta-spot
Horst Balthasar, Christian Beck, Rohan E. Louis +2
Sunspots, which harbor both magnetic polarities within one penumbra, are called delta-spots. They are often associated with flares. Nevertheless, there are only very few detailed o…
The energy of waves in the photosphere and lower chromosphere: III. Inversion setup for Ca II H spectra in local thermal equilibrium
C. Beck, R. Rezaei, K. G. Puschmann
The Ca II H line is one of the strongest lines in the solar spectrum and provides continuous information on the solar atmosphere from the photosphere to the lower chromosphere. We…
The signature of chromospheric heating in Ca II H spectra
C. Beck, W. Schmidt, R. Rezaei +1
We analyze a 1-hour time series of Ca II H intensity spectra and polarimetric spectra around 630 nm to derive the signature of the chromospheric heating and to investigate its rela…
