Abstract

One of the key goals in planetary science is to place the development of our own solar system in to the general development of planetary systems in the galaxy and universe. Disk winds, powered by magneto centrifugal acceleration of gas in an accreting disk, are a key candidate for explaining the redistribution of angular momentum in evolving planetary systems and for forming bipolar jets seen emanating from stars with accretion disks. A key observation of developing stellar systems is the association of collimated bipolar jets and the presence of accretion disks, leading to the concept that the jets are powered by the accretion of the material on to the central star. These parameters can be accommodated in a scenario based on magneto-centrifugally driven disk winds. Ions are accelerated along magnetic field lines and the impact of ions on solids causes frictional heating.
