Abstract
This research paper investigates the relationship between solar wind intensity and cosmic ray flux in the outer heliosphere, utilizing data from Voyager 1 and the Interstellar Boundary Explorer (IBEX). Voyager 1’s measurements beyond the heliopause, where the solar wind significantly weakens, show a marked increase in cosmic ray intensities, suggesting that solar wind acts as a modulating force. Meanwhile, IBEX's all-sky maps of energetic neutral atoms (ENAs) offer complementary data, demonstrating how the solar wind interacts with the interstellar medium at the boundary of the solar system. By analyzing the inverse correlation between solar wind strength and cosmic ray penetration into the heliosphere, this study provides a comprehensive understanding of the dynamic processes occurring at the solar system’s edge. The combined data from these missions not only enhance our understanding of space weather but also provide valuable insights into the broader interaction between the heliosphere and the interstellar medium. This research underscores the significance of continuous monitoring and multi-mission data integration for advancing our understanding of cosmic ray modulation and solar wind behavior in the outer reaches of the solar system.
