Query: Bayesian Analysis of Hot Jupiter Radius Anomalies: Evidence for Ohmic
  Dissipation?   The cause of hot Jupiter radius inflation, where giant planets with $T_{\rm
eq}$ $>1000$ K are significantly larger than expected, is an open question and
the subject of many proposed explanations. Rather than examine these models
individually, this work seeks to characterize the anomalous heating as a
function of incident flux, $\epsilon(F)$, needed to inflate the population of
planets to their observed sizes. We then compare that result to theoretical
predictions for various models. We examine the population of about 300 giant
planets with well-determined masses and radii and apply thermal evolution and
Bayesian statistical models to infer the anomalous power as a function of
incident flux that best reproduces the observed radii. First, we observe that
the inflation of planets below about $M=0.5 \;\rm{M}_\rm{J}$ appears very
different than their higher mass counterparts, perhaps as the result of mass
loss or an inefficient heating mechanism. As such, we exclude planets below
this threshold. Next, we show with strong significance that $\epsilon(F)$
increases with $T_{\rm{eq}}$ towards a maximum of $\sim 2.5\%$ at $T_{\rm{eq}}
\approx 1500$ K, and then decreases as temperatures increase further, falling
to $\sim0.2\%$ at $T_\rm{eff}= 2500$ K. This high-flux decrease in inflation
efficiency was predicted by the Ohmic dissipation model of giant planet
inflation but not other models. We also explicitly check the thermal tides
model and find that it predicts far more variance in radii than is observed.
Thus, our results provide evidence for the Ohmic dissipation model and a
functional form for $\epsilon(F)$ that any future theories of hot Jupiter radii
can be tested against.
