On the possibility of radio observations of current sheets on the sun
Abstract
The possibility of a discovery of current sheets in the radio band by using their screening and reflective properties as well as their own emission is discussed. It is shown that the thermal bremsstrahlung of the sheet may be of a sufficiently large intensity at the maximal critical frequency for the plasma in the sheet. Depending on electron density and temperature, the thickness of the sheet from tens of centimeters to hundreds of meters is sufficient to provide optical depth greater than or equal to a critical intensity. Spectral observations with sufficient angular resolution may give such characteristics of the sheet as its temperature, electron density, thickness and height in the solar atmosphere.
