Abstract
Motivated by the upcoming Solar Orbiter and Solar Probe Plus missions,
qualitative and quantitative predictions are made for the effects of the
violation of the Taylor hypothesis on the magnetic energy frequency spectrum
measured in the near-Sun environment. The synthetic spacecraft data method is
used to predict observational signatures of the violation for critically
balanced Alfv\'enic turbulence or parallel fast/whistler turbulence. The
violation of the Taylor hypothesis can occur in the slow flow regime, leading
to a shift of the entire spectrum to higher frequencies, or in the dispersive
regime, in which the dissipation range spectrum flattens at high frequencies.
It is found that Alfv\'enic turbulence will not significantly violate the
Taylor hypothesis, but whistler turbulence will. The flattening of the
frequency spectrum is therefore a key observational signature for fast/whistler
turbulence.
