We report on some ongoing projects with Hirshberg and also with Phillips and Wang, regarding the structure and classification of strongly outer actions of amenable groups on Jiang-Su stable C*-algebras. Most notably, we show that there exists a "model" strongly outer, strongly self-absorbing action that is absorbed by any strongly outer action. We will discuss applications to the theory of Rokhlin dimension, as well as preservation results for D-stability of crossed products.
