Solar electron events at Mars and solar radio bursts: Cross-mission study of MAVEN, Parker Solar Probe, and STEREO

Type III solar radio bursts are generated by energetic electron beams traveling along magnetic field lines and through solar corona, which can be observed as impulsive solar energetic particle (SEP) electron events, and are often associated with solar flares. The solar cycle has intensified since 2022, and multiple instruments have reported a clear increase in the frequency of radio bursts. In this project, we analyzed Parker Solar Probe (PSP) data to detect and catalog potential type III bursts from 2022 to 2023, calculating their frequency drift rates and analyzing their statistical distribution. In order to determine correlation between radio-frequency drift rates and energy-time evolution, this event catalog was cross-referenced with a list of impulsive electron events observed by the Mars Volatile EvolutioN (MAVEN) Solar Energetic Particle (SEP) instrument. To contextualize these events, we compared these recordings with GOES X-ray flux peaks and ultraviolet imagery of the Sun to monitored active regions. To assess how geometry affected detectability and timing, we determined alignment periods among spacecrafts and planetary bodies. We also employed a recognition-analysis system to automatically identify type III radio bursts through binarization and line detection techniques to discriminate between signals and background. These measurements were cross-compared with concurrent detections from STEREO and MAVEN, where we further investigated the relationship between frequency drift rates (PSP and STEREO) and energy drift rates (MAVEN). Together, this work turns routine radio bursts into a quantitative catalog and a cross-instrument analysis.
