Flare-induced changes of the photospheric magnetic field in a -spot deduced from ground-based observations
Peter Gömöry, Horst Balthasar, Christoph Kuckein +6
Aims: Changes of the magnetic field and the line-of-sight velocities in the photosphere are being reported for an M-class flare that originated at a -spot belonging to active re…
Demuth's path to randomness
Antonín Kučera, André Nies, Christopher P. Porter
Osvald Demuth (1936--1988) studied constructive analysis from the viewpoint of the Russian school of constructive mathematics. In the course of his work he introduced various notio…
Search for Alfvén waves in a bright network element observed in Halpha
J. Koza, P. Sütterlin, P. Gömöry +2
Alfven waves are considered as potential transporters of energy heating the solar corona. We seek spectroscopic signatures of the Alfven waves in the chromosphere occupied by a bri…
Magnetic loop emergence within a granule
P. Gömöry, C. Beck, H. Balthasar +4
We investigate the temporal evolution of magnetic flux emerging within a granule in the quiet-Sun internetwork at disk center. We combined IR spectropolarimetry performed in two Fe…
Low upper bounds of ideals
Antonin Kucera, Theodore A. Slaman
We show that there is a low T-upper bound for the class of K-trivial sets, namely those which are weak from the point of view of algorithmic randomness. This result is a special ca…
The height dependence of temperature - velocity correlation in the solar photosphere
J. Koza, A. Kucera, J. Rybák +1
We derive correlation coefficients between temperature and line-of-sight velocity as a function of optical depth throughout the solar photosphere for the non-magnetic photosphere a…
