Small-scale Magnetic Flux Ropes in the First two Parker Solar Probe Encounters

Yu Chen, Qiang Hu, Lingling Zhao +15

Small-scale magnetic flux ropes (SFRs) are a type of structures in the solar wind that possess helical magnetic field lines. In a recent report (Chen & Hu 2020), we presented the r…

Long-term variations of quasi-trapped and trapped electrons in the inner radiation belt observed by DEMETER and SAMPEX

Kun Zhang, Xinlin Li, Zheng Xiang +5

Electrons in the Earth's radiation belts can be categorized into three populations: precipitating, quasi-trapped and trapped. We use data from the DEMETER and SAMPEX missions and f…
