[AOS25-12] Bioparticle deposition at a stratospheric altitude
キーワード：成層圏、宇宙生物学、生物粒子
Understanding the dynamics of a bioparticle in the stratosphere is important to discuss astrobiological subjects such as the possibility of panspermia or the survivability of microbes in an extraterrestrial environment. In this presentation, the motion of a particle controlled by the gravity, air resistance, solar light pressure, the gravitational effect from the sun, and the photophoresis force with various diameters, densities, and drop heights will be discussed.
