The concept of “self-organized criticality” (SOC) has been introduced by Bak, Tang, and Wiesenfeld (1987) to describe the statistics of avalanches on the surface of a sandpile with a critical slope, which produces a scale-f ree powerlaw size distribution of avalanches. In the meantime, SOC behavior has been identified in many nonlinear dissipative systems that are driven to a critical state. On a most general level, SOC is the statistics of coherent nonlinear processe s, in contrast to the…

Statistical distributions of avalanche size and waiting times in an inter-sandpile cascade model
Sandpile-based models have successfully shed light on key features of nonlinear relaxational processes in nature, particularly the occurrence of fat-tailed magnitude distributions and exponential


Avalanches and the Distribution of Solar Flares
The solar coronal magnetic field is proposed to be in a self-organized critical state, thus explaining the observed power-law dependence of solar-flare-occurrence rate on flare size which extends
Logistic Avalanche Processes, Elementary Time Structures, and Frequency Distributions in Solar Flares
We analyze the elementary time structures (on timescales of ? 0.1-3.0 s) and their frequency distributions in solar flares using hard X-ray (HXR) data from the Compton Gamma Ray Observatory (CGRO)
Statistical Properties of SGR 1900+14 Bursts.
The analysis lends support to the hypothesis that the energy source for SGR bursts is internal to the neutron star and plausibly magnetic, and gives evidence for self-organized criticality in SGRs.
Statistics of X-Ray Fluctuations from Cygnus X-1: Reservoirs in the Disk?
X-rays from stellar black hole candidates, such as Cygnus X-1, are known to exhibit rapid time variations. Previously, these variations have seemed to occur at random. At a result, the "shot-noise
Statistical Analysis of the Energy Distribution of Nanoflares in the Quiet Sun
For many years it has been debated whether the quiet solar corona is heated by nanoflares and microflares or by magnetic waves. In this paper TRACE data of events with energies in the range 1023-1026
Extreme Ultraviolet Explorer Deep Survey observations of cool stars (spectral type F to M) have been used to investigate the distribution of coronal —are rates in energy and its relation to activity
Time Variability of the “Quiet” Sun Observed with TRACE. II. Physical Parameters, Temperature Evolution, and Energetics of Extreme-Ultraviolet Nanoflares
We present a detailed analysis of the geometric and physical parameters of 281 EUV nanoflares, simultaneously detected with the TRACE telescope in the 171 and 195 A wavelengths. The detection and
Frequency distributions and correlations of solar X-ray flare parameters
We have determined frequency distributions of flare parameters from over 12000 solar flares recorded with the Hard X-Ray Burst Spectrometer (HXRBS) on the Solar Maximum Mission (SMM) satellite. These
Energy Distribution of Heating Processes in the Quiet Solar Corona
We have determined the variations in the emission measure of the solar corona using EUV Imaging Telescope/Solar and Heliospheric Observatory observations of iron lines in a quiet region of the Sun.
Deep Survey of Solar Nanoflares with Yohkoh
Short timescale variability fainter than transient brightenings (microflares) is found in the solar position-dependent light curves observed with the Yohkoh Soft X-Ray Telescope. The time variability
