<div><br>
</div>
<div>Our paper entitled "Power-law Statistics of Driven Reconnection in the Magnetically Closed Corona" was just published in ApJ at <a href="http://iopscience.iop.org/article/10.3847/1538-4357/aaa0d9" target="_blank">http://iopscience.iop.org/article/10.3847/1538-4357/aaa0d9</a></div>

</div>
<div>It may be of interest to those studying loop models, reconnection in Parker coronae, as well as to modelers of self-organized criticality.<br>

<p style="font-size: 13px;"><span style="font-size: 9pt;">Numerous observations have revealed that power-law distributions are ubiquitous in energetic solar processes. Hard X-rays, soft X-rays, extreme ultraviolet radiation, and radio waves all display power-law
frequency distributions. Since magnetic reconnection is the driving mechanism for many energetic solar phenomena, it is likely that reconnection events themselves display such power-law distributions. In this work, we perform numerical simulations of the solar
corona driven by simple convective motions at the photospheric level. Using temperature changes, current distributions, and Poynting

We suggest that the braiding-associated reconnection in the corona can be understood in terms of a self-organized criticality model driven by convective rotational motions similar to those observed at the photosphere. </span></p>
