The choice of the subject was made because of an apparent similari- ty - stressed already at earlier meetings - of four classes of astrophy- sical jet sources: Active Galactic Nuclei, Young Stellar Objects, Binary Neutron Stars and Binary White Dwarfs. They share important properties such as their morphology, high variability and large veloci- ty gradients as well as - with some inference - their broad spectrum, hypersonic outflow and core\/lobe power ratio. Despite this apparent similarity of the four source classes, quite different models have been put forward for their description: (i) The central engine of active galactic nuclei has been generally thought to be a black hole, in contrast to the central engine of young stellar objects and cometary nebulae which apparently is a pre-T-Tauri star, some six orders of magnitude less compact, and to the central engine of planetary nebulae which mayor may not be a binary white dwarf. (ii) The elongated lobes, or flow patterns, have been often interpreted as highly directional stellar wind outflows whereas in a few well- mapped cases, the elongated flow appears to be 'pumped up' through a much narrower channel, or jet, both in the extragalactic and stellar sources.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45282213789847,"sku":"9789401082426","price":10900.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789401082426.webp?v=1769301484","url":"https:\/\/atlanticbooks.com\/products\/astrophysical-jets-and-their-engines-9789401082426","provider":"Atlantic Books","version":"1.0","type":"link"}
