The Ideal

It is shown that a logarithmic feature in the low-frequency asymptotics of the spectral energy distribution of the equilibrium radiation in an electron plasma occurs with arbitrary degeneration of electrons within the framework of the ideal gas approximation for the transverse dielectric permittivity.

AbstractHere we consider the influence of microlensing on the spectrum of a lensed object with the angular size 5 μas accepting that the composite emission of this object originates from three different regions arranged around its center. We assume that the lensed object has three concentric regions with a black-body emission; the temperatures of these regions are 10 000 K, 7500 K and 5000 K. We investigate how the integral spectral energy distribution (SED) of such stratified source changes due to microlensing by a group of solarmass stars. We find that the SED and flux ratios in the photometric B, V and R passbands show considerable changes during a microlens event. This indicates that the flux anomaly observed in some lensed quasars may be caused by microlensing of a stratified object.
