Probing the Kosterlitz-Thouless transition in 1D Heisenberg antiferromagnet based on topological properties of its ground state
P. Tomczak, P. Jablonski, M. Tomczak
A Kosterlitz-Thouless phase transition in the ground state of an antiferromagnetic spin- Heisenberg chain with nearest and next-nearest-neighbor interactions is re-inv…
Flare Hybrids
M. Tomczak, P. Dubieniecki
Svestka (Solar Phys. 1989, 121, 399) on the basis of the Solar Maximum Mission observations introduced a new class of flares, the so-called flare hybrids. When they start, they loo…
Multiperiodicity in quasi-periodic pulsations of flare hard X-rays: a case study
M. Tomczak, Z. Szaforz
We present a case study of the solar flare (SOL2001-10-02T17:31) that showed quasi-periodic pulsations (QPPs) in hard X-rays with two simultaneously excited periods, P_1 = 26-31 s…
Investigation of the X-ray Emission of the Large Arcade Flare of 2 March 1993
Jerzy Jakimiec, Michal Tomczak
A large arcade flare of 2 March 1993 has been investigated using X-ray observations recorded by the {\sl Yohkoh} and GOES satellites and the {\sl Compton Gamma Ray Observatory}. We…
Simultaneous Yohkoh/SXT and TRACE Observations of Solar Plasma Ejections
E. Chmielewska, M. Tomczak, T. Mrozek
We investigated the relationship between hot (~10 MK) and warm (~1 MK) plasma ejections observed in the solar corona during some flares from April 1998 to December 2001. Based on t…
Two solar flares that became X-ray plasma ejections
Michal Tomczak
Solar flares and X-ray plasma ejections (XPEs) occur simultaneously but usually are separated spatially. We present two exceptional events observed by {\sl Yohkoh} in 2001 October…
