Abstract
The observational evidence for an association between energetic bipolar outflows in Young Stellar Objects and circumstellar accretion disks is summarized, and arguments are presented in favor of a model in which this apparent connection is attributed to the winds being centrifugally driven outflows that act as the main angular momentum transport mechanism in the disks. In this picture, the wind is accelerated by interstellar magnetic field lines that thread the differentially rotating disk. The kinematic and thermal properties of the winds are discussed and are shown to account naturally for many of the distinctive radiative properties of these objects. The implications of these results to jets in active galactic nuclei are also briefly considered.KeywordsAccretion DiskActive Galactic NucleusTauri StarCircumstellar DiskYoung Stellar ObjectThese keywords were added by machine and not by the authors.
