Planetary shielding and surface precipitation of solar energetic particles during BepiColombo's close Mercury flyby

Planetary magnetic fields act as protective barriers, shielding a planet’s atmosphere and surface from energetic charged particles originating from its parent star and outer space. During its fourth flyby of Mercury on 4 September 2024, the ESA/JAXA …

Calibration of the BepiColombo environmental radiation monitor (BERM) and cross-calibration with solar intensity X-ray and particle spectrometer (SIXS) during solar energetic particle events

The BepiColombo Environment Radiation Monitor (BERM) is a housekeeping instrument onboard the BepiColombo mission, capable of measuring electron, proton, and heavy-ion fluxes. Due to its quasi-continuous data acquisition throughout all mission …

Peak-intensity energy spectra of intense solar energetic electron events measured with Solar Orbiter in 2020─2022 (Corrigendum)

Catalogue and statistics of > 100 MeV solar proton events during solar cycles 23─25 from SOHO/ERNE observations

*Context.* The SPEARHEAD (specification, analysis, and re-calibration of high-energy particle data) project, funded by the European Union’s Horizon Europe programme, enhances the accuracy and usability of high-energy particle measurements. It …

Peak-intensity energy spectra of intense solar energetic electron events measured with Solar Orbiter in 2020─2022

*Context.* The energy spectra of energetic particles offer valuable insights into particle acceleration processes. While the commonly observed spectral breaks in solar energetic electron (SEE) spectra could serve as fingerprints of the acceleration …

Superposed epoch analysis of solar energetic particle events observed in solar cycle 25

Intensity-time profiles of solar energetic particles (SEPs) emitted during solar eruptions are shaped by a number of entangled processes. This involves the location of the particle source with respect to the observer, the type, location, and duration …

Comparing observations of closely located JUICE and STEREO-A spacecraft during the widespread 13 May 2024 solar energetic particle event

*Context.* Following its launch in April 2023, JUICE is now in its cruise phase to Jupiter, where it is scheduled to arrive in July 2031. JUICE carries a radiation monitor, namely the RADiation hard Electron Monitor (RADEM) to measure protons, …

A statistical study of energetic particle events associated with interplanetary shocks observed by Solar Orbiter in solar cycle 25

*Context.* We studied energetic particle intensity profiles observed by Solar Orbiter during the time period from April 2020 to April 2023, associated with the passage of interplanetary (IP) shocks. For our study we considered 58 IP forward shocks …

BepiColombo cruise science: overview of the mission contribution to heliophysics

BepiColombo, the joint ESA/JAXA mission to Mercury, was launched in October 2018 and is scheduled to arrive at Mercury in November 2026 after an 8-year cruise. Like other planetary missions, its scientific objectives focus mostly on the nominal, …
