We reexamine the energetics of nonthermal-electron acceleration in solar noise storms. A new result is obtained for the minimum nonthermal-electron number density required to produce a Langmuir-wave population of sufficient intensity to power the noise-storm emission. We combine this constraint with the stochastic electron acceleration formalism developed by Subramanian and Becker (2005) to derive a rigorous estimate for the efficiency of the overall noise-storm emission process, beginning with nonthermal-electron acceleration and culminating in the observed radiation. We also calculate separate efficiencies for the electron acceleration–Langmuir wave generation stage and the Langmuir wave–noise-storm production stage. In addition, we obtain a new theoretical estimate for the energy density of the Langmuir waves in noise-storm continuum sources. |
