In 1-D heat conductivity model, the YORP acceleration is proved to be independent of the asteroid's heat properties. Considering small structures on the surface of an asteroid breaks 1-D model. A new force appears, pulling the asteroid's surface parallel to itself. Its effect on the asteroid's rotation is called tangential YORP, or TYORP.
