Abstract:
We show that there exists apparent contradiction between the temperature spectra derived from the Spektr-R data and the temperature spectra predicted theoretically. We show that the temperature uctuations can be correctly estimated from the Spektr-R data only if the mean temperature is isotropic. Since the mean temperature in the solar wind is usually anisotropic, the derived uctuations appear to be pseudo-temperature rather than temperature. These pseudo- temperature uctuations are driven by the high-amplitude magnetic uctuations in Alfven waves rather than the uctuations of temperature or thermal velocity.
