The Jets,can be destroyed by neutral intruders, such as photons and hydrogen atoms. The possibility of in-situ acceleration of electrons in their hotspots, the correct form of the relativistic beaming law and the confinement problem are discussed.

T Tauri Stars, Pre-T Tauri Stars, and Stellar Jets,e “pre-T Tauri stars”, are thought to be the stars responsible for exciting Herbig-Haro objects. Pre-T Tauri stars are capable of generating “stellar jets” by which bipolar flows carry material out into the ambient medium out of which low-mass stars form. Manifestations of these bipolar flows are: s作者: nurture 時間: 2025-3-23 00:12 作者: 單獨 時間: 2025-3-23 02:36

Foucault: Diskursanalyse der PolitikIn this lecture I shall discuss the observational evidence relevant to the speeds of jets in radio galaxies and quasars. My conclusion is that the outer jets of weak (FR I) sources have non-relativistic speeds, while jets in strong (FR II) sources have speeds comparable with the speed of light, and perhaps very close to the speed of light.作者: 稱贊 時間: 2025-3-26 13:12
