Gravitational instabilities in circumstellar disks
Star and planet formation are the complex outcomes of gravitational collapse and angular
momentum transport mediated by protostellar and protoplanetary disks. In this review, we …

Theory of star formation
CF McKee, EC Ostriker - Annu. Rev. Astron. Astrophys., 2007 - annualreviews.org
We review current understanding of star formation, outlining an overall theoretical framework

Dynamics of protoplanetary disks
PJ Armitage - Annual Review of Astronomy and Astrophysics, 2011 - annualreviews.org
Protoplanetary disks are quasi-steady structures whose evolution and dispersal determine
the environment for planet formation. I review the theory of protoplanetary disk evolution and …
