v41 v42 61 61 The ram pressure in the light ambient case does not build up outside of the sphere at all, which is in accordance with the above statement that the material in the ambient, while moving inward, is carrying no momentum. Inside the ram pressure is fluctuating in a manner that coincides with the radial velocity and density plots in this region. At all times, the ram pressure is well below the critical value. 62 62 63 In the matched ambient case, however, Pram>Pcrit only after t~2.3 myrs. By t =3 myrs, the Pram profile has taken on a very unique cowboy hat appearance. 63 In the matched ambient case, however, Pram>Pcrit only after t~2.3 myrs. By t =3 myrs, the Pram profile has taken on a very unique "cowboy-hat" appearance. Another look at the radial velocity plots and the density plots show that this is due to the high increase in density inside of the sphere by t=3myrs with small concomitant radial velocities, while outside of the sphere there are small density buildups coinciding with a large vrad, which when squared for Pram gives a large Pram outside as well. 64 65 66 '''Discussion''' 67 68 -The ram pressure does not seem to be as dominant a factor in inducing collapse, rather the thermal pressure almost immediately exceeds Pcrit.. Thus it may be better to approximate tc as much earlier on. 69 70 -Next step may to better characterize Rbe, as it is moving in with time.. 71 72 -size differences, computational difficulties, etc. 73 64 74 65 75 … … 70 80 '''''Mesh-''''' 71 81 72 The movies shown below are just of the time frames up until the collapse in the matched case became poorly resolved.
