AB  - The properties expected of “hot” non-flaring plasmas due to nanoflare heating in active regions areinvestigated using hydrodynamic modeling tools, including a two-fluid development of the EBTELcode. Here we study a single nanoflare and show that while simple models predict an emission measuredistribution extending well above 10 MK that is consistent with cooling by thermal conduction,many other effects are likely to limit the existence and detectability of such plasmas. These include:differential heating between electrons and ions, ionization non-equilibrium and, for short nanoflares,the time taken for the coronal density to increase. The most useful temperature range to look for thisplasma, often called the “smoking gun” of nanoflare heating, lies between 106.6 and 107 K. Signaturesof the actual heating may be detectable in some instances.
