On the extreme stationary outflows from super star clusters:: From superwinds to supernebulae and further massive star formation

Here we discuss the properties of star cluster winds in the supercritical, catastrophic cooling regime. We demonstrate that catastrophic cooling inhibits superwinds and that after a rapid phase of accumulation of the ejected material within the star-forming volume, a new stationary isothermal regime, supported by the ionizing radiation from the central cluster, is established. The expected appearance of this core/halo supernebula in the visible-line regime and possible late evolutionary tracks of super star cluster winds in the absence of ionizing radiation are thoroughly discussed.
