Narrowband Spikes Observed during the 2013 November 7 Flare

Marian Karlický, Jan Benáček, Ján Rybák

Narrowband spikes are observed in solar flares for several decades. However, their exact origin is still discussed. To contribute to understanding of these spikes, we analyze the n…

Flare Expansion to a Magnetic Rope Accompanied by Rare Radio Bursts

Alena Zemanová, Marian Karlický, Jana Kašparová +1

We present multispectral analysis (radio, H, UV/EUV, and hard X-ray) of a confined flare from 2015 March 12. This flare started within the active region NOAA 12 297 and then it…

Expansion of Hot Plasma into Cold Plasma

Jan Benáček, Marian Karlický

The X-ray emission of coronal flare sources can be explained considering the kappa electron distribution. Motivated by this fact, we study the problem of how hot plasma with the ka…

Brightness Temperature of Radio Zebras and Wave Energy Densities in Their Sources

Leonid V. Yasnov, Jan Benáček, Marian Karlický

We estimated the brightness temperature of radio zebras (zebra pattern -- ZP), considering that ZPs are generated in loops having an exponential density profile in their cross-sect…

Temperature dependent growth rates of the upper-hybrid waves and solar radio zebra patterns

Jan Benáček, Marian Karlický, Leonid V. Yasnov

Context. The zebra patterns observed in solar radio emission are very important for are plasma diagnostics. The most promising model of these patterns is based on double plasma res…

Torsional oscillations and observed rotational period variations in early-type stars

J. Krticka, Z. Mikulasek, G. W. Henry +2

Some chemically peculiar stars in the upper main sequence show rotational period variations of unknown origin. We propose these variations are a consequence of the propagation of i…
