Radiation Pressure Force on Non-spherical (Disk-type) Dust Particle

More about the book

The study explores the radiation pressure force on non-spherical dust particles, specifically water ice, magnetite, and silicate, using the Discrete Dipole Approximation method. It examines how solar radiation and solar wind pressures influence solid bodies ranging from 0.1 m to 100 m in the interplanetary space, particularly focusing on the early solar system when the solar wind pressure was stronger than radiation pressure. The research highlights the dominance of the pseudo-Poynting-Robertson effect during this period, emphasizing the complex interactions between solar forces and dust particles.
