ANOMALOUS COMET TAILS AND THE 11-YEAR SOLAR ACTIVITY CYCLE

Abstract

The ar­tic­le analy­zes the sta­tis­ti­cal as­pects of the for­ma­ti­on of ano­ma­lo­us co­met ta­ils. The sta­te of so­lar ac­ti­vity du­ring the for­ma­ti­on of 97 ano­ma­lo­us ta­ils was stu­di­ed. It was fo­und that in long-pe­ri­od co­mets such ta­ils are ob­ser­ved du­ring the pe­ri­od of dec­rea­sing ac­ti­vity (pha­se 0.75), and in short-pe­ri­od co­mets - im­me­dia­tely af­ter the ma­xi­mum (pha­se 0.55). This fact is im­por­tant to ta­ke in­to ac­co­unt in the study of the physics and evo­lu­ti­on of co­mets.
