The Impact of Space Radiation on Brains of Future Martian and Lunar Explorers
Published 2023-10-01“…Our calculations show that GCR induced absorbed dose per month in the brain does not reach the 30‐day limit for CNS (500 mGy) as defined by NASA on either Martian or lunar surface. Based on the spectra and frequency of historical extreme SEP events recorded at Earth as ground‐level enhancement events over past five solar cycles, our results suggest that the CNS of astronauts will be generally “safe” on the Martian surface, but those on the lunar surface or in deep space may face radiation risks in their CNS if not well shielded during such extreme events.…”

Metallicity Dependence of Giant Planets around M Dwarfs
Published 2025-01-01“…All metallicity measurements are homogeneously obtained through the same methodology based on the near-infrared spectra collected with a single instrument SpeX mounted on the NASA Infrared Telescope Facility. We find that (1) giant planets favor metal-rich M dwarfs at a 4 σ –5 σ confidence level, depending on the band of spectra used to derive metallicity; (2) hot ( a / R _* ≤20) and warm ( a / R _* > 20) Jupiters do not show a significant difference in the metallicity distribution. …”
