Influence of the UV Environment on the Synthesis of Prebiotic Molecules
Ultraviolet (UV) radiation is common to most planetary environments, and could play a key role in the chemistry of molecules relevant to abiogenesis (prebiotic chemistry). In this work, we explore […]

Effects of Turbulent Dust Grain Motion to Interstellar Chemistry
Theoretical studies have revealed that dust grains are usually moving fast through the turbulent interstellar gas, which could have significant effects upon molecular cloud chemistry by modifying grain accretion. This […]
