Preprint Models Cosmic Ray Impact on Planetary Atmospheres

A new preprint, accepted for publication in Astronomy & Astrophysics, details a study on cosmic ray energy deposition in planetary and exoplanetary atmospheres. Using the CosmicTransmutation code, researchers modeled how planetary magnetic fields affect galactic cosmic rays and stellar energetic particles. This research is significant as these interactions can alter atmospheric composition and impact the detectability of biosignatures.
