Jets are a largely common phenomenon and reveal themselves at different scales and redshifts, showing an extreme diversity in energetics, shapes and emission, in objects such as active galactic nuclei (AGN) and X-ray binaries (XRBs), young stellar objects (YSOs), pre-planetary nebulae (PPNe) and so on.
Observations suggest that jets are an energetically important component, not only to the systems that host them, but also their larger surrounding environments, where they deposit a significant amount of energy that has been extracted from the accretion flow.
Therefore, understanding the mechanisms responsible for the formation and emission of jets is a fundamental problem to be addressed.
In this talk, I will present my most recent study on the non-relativistic MHD equations describing collimated disk-driven outflows.
For the first time, jet solutions can be reconstructed from the disk mid-plane to downstream of the modified magnetosonic fast point, where they end with a recollimation shock.
These solutions show a range of jet dynamics, which makes this model suitable for application to many different systems in which non-relativistic jets are launched. I will discuss the application to the preplanetary nebula W43A to show how the solutions can be used to constrain MHD derived properties.
