Theory of pulsar winds and nebulae - Max-Planck
... According to conventional wisdom, an enormous electric field is induced by the rotation of a magnetised neutron star. This field tears particles from the stellar surface and accelerates them up to high energies. As a result, these “primary” particles initiate an electron-positron cascade, which popu ...

The chemical case for no winds in dwarf irregular galaxies
... gas-rich dwarf galaxies, not affected by external environmental processes. One of the agents that may regulate the star formation history of these objects is the presence of strong galactic winds. If they have a low mass and a high star formation rate (SFR), the energy injected by supernova (SN) exp ...

The difficulty of forming large disk galaxies with small bulges
... Binney, Fraternali, Marinacci et al (2006 ff) propose that SN-driven fountain gas entrains hot halo material which returns to the disk. Star formation sustains itself from the hot halo, with accretion rate ~ 2 M yr-1 in the Milky Way. (Deposition rate is smaller than the overall rate of interchang ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
