摘要: Abstract Observations by several instruments onboard the Cassini spacecraft revealed existence of heavy hydrocarbon and nitrile species with masses thousand atomic mass units in ionosphere Titan. These very large molecules are fact aerosols. The goal this paper is to compute concentrations charged aerosols upper atmosphere (950–1200 km) charging these has been studied using charge balance equations, where positive ions, negative electrons, neutral included. Number compared those observed instruments. present work estimates aerosol density as 1–10 kg/m3, which within predicted range. results show that must be smaller than 10 nm order have reasonable agreement observations Plasma Spectrometer.
