THE BRIGHTNESS OF FLOCCULI, MAGNETIC FIELDS AND MECHANISMS OF HEATING,
Abstract
For fields with H less than 70 gauss the brightness of flocculi increases in the mean with the increase in field strength. For fields with H greater than 70 gauss the brightness of the flocculi decreases with increasing field strength. The study of the change of the form of flocculi and the magnetic field with time showed that the magnetic field influences the formation of flocculi. There are two mechanisms of flocculi formation. The first is connected with the development of rapid processes: flares and possibly moustaches. The second mechanism is also of an electromagnetic nature and is evidently connected with the absorption of the disturbances in the regions where the field strength carried by the wave is larger than the strength of the external field. The strength of the magnetohydrodynamic wave has been estimated. The difficulties met with by the explanation of the heating of flocculi as a result of the absorption of magnetohydodynamic waves are enumerated. (Author)
