- Abstract
The Theory of Alfven drag (Drell et al. in J Geophys Res 70: 3131-3145 ; Anselmo and Farinella in Icarus, 58, 182-185 ) is applied here to show that the existence of a possible solar ring structure at a radial distance of 0.02 AU (~4R, R = radius of the sun) predicted by earlier authors (Brecher et al. in Nature 282, 50-52 ; Rawal in Bull. Astr. Soc. India 6, 92-95 , Moon Planets 24, 407-414 , Moon Planets 31, 175-182 , J Astrophys Astr 10, 257-259 ) may not survive Alfven drag produced during even moderate solar magnetic storms which take place from time to time through the age of the sun, but a possible solar ring structure at a radial distance of 0.13 AU (~27R) (Brecher et al. in Nature 282, 50-52 ; Rawal in Bull. Astr. Soc. India 6, 92-95 , Moon Planets 24, 407-414 , Moon Planets 31, 175-182 , J Astrophys Astr 10, 257-259 ) may survive intense Alfven drag produced during even strong magnetic storms of magnetic field value up to 1,000 G.
