Definition

The disk midplane corresponds to the region of a circumstellar disk where the vertical density distribution peaks. The midplane is thought to be the coldest region of the disk, due to the inability of stellar radiation to penetrate deeply. The low temperatures and high densities lead to the fastest growth timescales for planetesimals and result in planets with coplanar orbits (if no scattering or inclination pumping occurs).
