Interacting Jets from Binary Protostars
Aims. We investigate potential models that could explain why multiple proto-stellar systems predominantly show single jets. During their formation, stars most frequently produce energetic outflows and jets. However, binary jets have only been observed in a very small number of systems. Methods. We model numerically 3D binary jets for various outflow parameters. We also model the propagation of ...
متن کاملEffect of the temperature profile of the accretion disk on the structure of jets and outflows around protostars
Magnetic fields play an important role in creating, driving, and in the evolution of outflows and jets from protostars and accretion disks. On the other hand, the temperature profile of the accretion disks may also affect the structure of the magnetic field and outflows. In this paper, we use the self-similar method in cylindrical coordinates to investigate the effect of the temperature profile...
متن کاملJets and Outflows From Advective Accretion Disks
Jets and outflows must be produced directly from accretion disks and inflows, especially when the central gravitating objects are compact, such as neutron stars and black holes, and themselves are not mass losing. Here, we review the formation of jets from advective inflows. We show that the centrifugal pressure supported boundary layer (CENBOL) of the black holes may play crucial role in produ...

متن کاملChapter 10 Jets and Outflows
The ejection of prodigious amounts of material during birth still puzzles us. It is paradoxical that just when we expect to observe infall, the signatures of outflow prevail. Ultimately, we want to know why. Are we witnessing simply the disposal of waste material – the placenta being cast aside? Or are outflows essential, a means of removing some ingredient which allows the rest to flow inwards...
