Statistical Properties of Flaring and Sub-flaring Activity in the Solar Atmosphere
نویسنده
چکیده
We review the observational, theoretical, and numerical efforts to interpret the statistical behavior of solar flares and sub-flares, and their role to coronal heating. The observed X-ray flares cannot heat the corona. The role of smaller-scale events is still inconclusive, although very recent observational evidence may shed light to the controversy. Statistical and classical modeling reproduces the statistics of large flares. Part of these models also predict a statistical behavior for the small-scale events consistent with that of Parker’s nanoflares if these events indeed heat the solar corona.

Relationship between Hyperactivity of Depressor Septi Nasi Muscle and Changes of Alar Base and Flaring during Smile
BACKGROUND Hyperactivity of depressor septi nasi muscle leads to smiling deformity and nasal tip depression. Lateral fascicles of this muscle help in widening the nostrils. The purpose of this study was to evaluate the relationship between the nasal length changes and the alar base and the alar flaring changes during smile. METHODS Standard photographs are performed in the face and lat...
متن کاملVariability of the occurrence frequency of solar flares and the statistical flare
Self-Organised Criticality (SOC), embedded in cellular automata models, has been so far viewed as an attractive phenomenological approach for studying the statistical behaviour of flaring activity in solar active regions. Well-known statistical properties of flares, like the robust scaling laws seen in the distribution functions of characteristic parameters of the events, as well as correlation...
متن کاملThe Energetics of a Flaring Solar Active Region, and Observed Flare Statistics
A stochastic model for the energy of a flaring solar active region is presented, generalising and extending the approach of Wheatland & Glukhov (1998). The probability distribution for the free energy of an active region is described by the solution to a master equation involving deterministic energy input and random jump transitions downwards in energy (solar flares). It is shown how two obser...
متن کاملA Fifteen Year Record of Global Natural Gas Flaring Derived from Satellite Data
We have produced annual estimates of national and global gas flaring and gas flaring efficiency from 1994 through 2008 using low light imaging data acquired by the Defense Meteorological Satellite Program (DMSP). Gas flaring is a widely used practice for the disposal of associated gas in oil production and processing facilities where there is insufficient infrastructure for utilization of the g...
متن کاملDiscovery of Solar Rieger Periodicities in Another Star
The Rieger periods are solar cycles with a time scale of months, which are present in both flaring activity and sunspot occurrence. These short-term periodicities, tentatively explained by equatorially trapped Rossby-type waves modulating the emergence of magnetic flux at the surface, are considered a peculiar and not yet fully understood solar phenomenon. We chose a stellar system with solar c...
