Abstract:In this letter we report the results of the first systematic study of a population of suprathermal electrons in the solar wind, called the 90° pitch angle enhancements. This feature was found in the vicinity of interplanetary shocks. We analyzed 2 hours time intervals centered on the shocks. The enhancements were found at 114 of 232 shocks (49 %), which means that this is a common feature. Statistical analysis of shock properties show no important differences between the shocks associated with the enhancements and those not associated with them. Preliminary analysis of electric field fluctuations revealed possible correlation between the presence of 90° PA enhancements of suprathermal electrons and the wave activity.

Title:90° PA ojačitve supertermičnih elektronov v bližini medplanetarnih udarnih valov
Abstract:V tem pismu poročamo o prvi sistematični študiji tipa populacije supertermičnih elektronov v sončevem vetru, imenovane ojačitve pri 90° PA (ang. pitch angle). Ta populacija je bila najdena v bližini medplanetarnih udarnih valov, pri čemer smo analizirali dvourne časovne intervale centrirane na udarnih valovih. Ojačitve pri 90° PA smo našli pri 114 od 232 (49 %) dogodkov, kar pomeni, da je ta tip populacije dokaj pogost v sončevem vetru. Statistična analiza lastnosti medplanetarnih udarnih valov je pokazala, da ni bistvenih razlik v lastnostih med udarnimi valovi ob katerih so bile ojačitve prosotne in tistimi kjer jih ni bilo. Preliminarna analiza fluktuacij električnega polja pa je pokazala, da je njihova aktivnost intenzivnejša v bližini udarnih valov, ob katerih smo našli ojačitve pri 90° PA.
Keywords:medplanetarni udarni valovi, supertermični elektroni, ojačitve pri 90° PA
