A Review of Circumstellar Discs

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

It is now accepted that stars form from collapsing molecular cloud cores and that they are typically surrounded - at early times - by circumstellar discs that have lifetimes of a few million years. These discs are thought to go through a number of different phases. During the earliest stages of star formation they are expected to evolve through disc self-gravity and may undergo a number of outbursts. The magnetorotational instabilty is thought to dominate at later times and may occur, initially at least, in the upper, ionised layers of the discs. The final stages evolve through dispersal via a disc wind, driven by photoevaporation. I will review, here, the evolution of these discs and will discuss some observations that support this general picture.
