... If this material collapses down under gravitational instability to being just 1au across, then the product 1pc.1km/s is conserved meaning the rotational velocity at 1au must be ~200,000km/s=0.66c! To actually collapse to 1AU (let alone the surface of the protostar ~0.005AU) angular momentum has to b ...

... structed, for a total of 97.7%. We observe 100m0 -ms 5 = 1005.40-5.445 = 96.38%, which is close considering we only two significant digits in the times. If we instead imagine that the larger star is hotter, so that the primary eclipse occurs when the smaller star is in front, we find that the ...
