Clearing the dust of the disc
Posted: Fri Dec 03, 2010 3:24 pm
The t tauri wind blows out at the poles of the forming star. Material from the disc is being drawn into the central hub. Material from the outer reaches of the original cloud fragment is also still falling in. This material, along with the heat and pressures generated when the sphere of hot gasses first fell into a disc shape, cannot be contained by gravity and the excess blows out of the pro to star at both poles. This is the t tour wind
My question is ... How does the wind move across the disc if it is heading in perpendicular directions? Does the wind start out moving at right angles and then spread out in all directions. If so, at what distance outward does it hit the disc, like .5 AU? Does the wind help push material into the mid plane of the disc?
Later, as nuclear fusion progresses and the modern solar wind pushes outward, does this wind also escape along the poles and then move in all directions or does it emanate spherically? Is it this solar wind that resists disc material from continuing to be gravitationally pulled in to the sun?
Which wind cleared out most of the dust? Didn't one of these wind push a lot of dust and gas from the inner reaches of the solar system out to the frost line at Jupiter?
