标题： On the Formation and Dynamics of Mass Outflux from Matter Accreting onto Compact Objects

摘要： 活动星系核和类星体被认为在其中心隐藏着黑洞，同时通过宇宙射电喷流以巨大的物质和能量从星系核心喷发出来。 在我们的工作中，我们计算了围绕黑洞的粘滞性吸积盘的质量外流率，这在原则上可以自洽地解释喷流形成的起源。 这些计算使用了精确的跨音速内流和外流解的组合完成，这些解可能形成冲击波，也可能不形成。 我们计算的方法与迄今为止文献中使用的方法有所不同。 我们的工作首次自洽地连接了吸积型和风型拓扑结构。 我们的结果总体上与数值模拟工作相匹配，并成功指出了可能导致盘状结构消失从而产生平静状态的非稳态行为。 显示英文摘要

摘要： Active galaxies and quasers are believed to harbour Black Holes at their centers and at the same time produce cosmic radio jets through which immense amount of matter and energy are ejected out of the core of the galaxy. In our work we compute the mass outflow rates from advective accretion disks around black holes, which, in principal could explain the origin of jet formation in self-consistent manner. These computations are done using combinations of exact transonic inflow and outflow solutions which may or may not form shock waves. The approach of our calculation is somewhat different from that used in the literature so far. Our work for the first time connects the accretion type and wind type topologies self consistently. Our result, in general, matches with numerical simulation works and successfully points out to non-steady behavior which may evacuate the disk producing quiescene states.
