$\begin{figure} \par\includegraphics[width=8.8cm,clip]{1971fig2.eps} \end{figure}$ Figure 2: Plot of $t_{\rm p}$ , $t_{\rm sp}$ , $t_{\rm c,A}$ , and $t_{\rm c,B}$ as a function of $\dot{M}_{\rm acc}$ . We used $r_{\rm d}=R_{\rm crit}$ to calculate $t_{\rm p}$ , and $r_{\rm d}=4\times R_{\rm crit}$ to calculate $t_{\rm sp}$ , $t_{\rm c,A}$ , and $t_{\rm c,B}$ . The vertical line indicates the value of $\dot{M}_{\rm acc}$ for which $R_{\rm crit}=125\:{\rm AU}$ . The environment density was set to $n_{\rm e}= 10^5~{\rm cm}^{-3}$ . See Sect. 6 for the values of other parameters.

$\begin{figure} \par\includegraphics[width=8.8cm,clip]{1971fig3.eps} \end{figure}$ Figure 3: Color scale plot of $\log_{10}$ of the density ( $\mbox{g}~\mbox{cm}^{-3}$ ) at t=9.0 yr for several two-dimensional wind-disk simulations using either the cooling curve module ( left hand side) or a low value of gamma ( $\gamma =1.1$ , top right; $\gamma =1.05$ , bottom right) to simulate radiative cooling. Parameters for initial densities and temperatures can be found in Table 1. Actual values of the density range from $4.0\times 10^{-20}$ to $1.25\times 10^{-15}$ ( top row) and from $3.2\times 10^{-20}$ to $7.9\times 10^{-15}$ $\mbox{g}~\mbox{cm}^{-2}$ ( bottom row). The size of the domain is 334 $\mbox{AU}^2$ , and a total of eight levels of refinement were used resulting in an effective resolution of 2048² cells. For the run with $\gamma =1.1$ we show the AMR grid structure superimposed on the density plot (only the finest four levels of refinement are visible, every grid consists of 16² cells). In the bottom right plot we show the initial shape of the disk superimposed.

$\begin{figure} \par\includegraphics[height=21cm,clip]{1971fig5.eps} \end{figure}$ Figure 5: Color scale plots of $\log_{10}$ of the density ( $\mbox{g}~\mbox{cm}^{-3}$ ) at t=0 yr ( first row), t=3 yr ( second row), t=6 yr ( third row), t=9 yr ( fourth row), and t=12 yr ( fifth row). Actual values of the density range from $3.0\times 10^{-21}$ to $1.0\times 10^{-16}$ $\mbox{g}~\mbox{cm}^{-3}$ . The size of the domain is 334 $\mbox{AU}^3$ , and a total of six levels of refinement were used resulting in an effective resolution of 512³ cells (each individual grid contained 16³ cells). Shown are cuts through the centre of the data cube in the xy-plane ( left column), xz-plane ( middle column), and yz-plane ( right column). The plots for the yz-plane show the grid structure superimposed where only the three finest levels of refinement are visible (coarser levels are fully refined). The corresponding isosurfaces are shown in Fig. 4.

$\begin{figure} \par\includegraphics[width=17cm,clip]{1971fig6.eps} \end{figure}$ Figure 6: Grey scale plots of the synthesized H $\alpha$ images (inverted; darker shades represent higher emission rates). Different projections of the three-dimensional data cube at $t=12~{\rm yr}$ are shown. The size of each box is $334~{\rm AU}^2$ and the $\log_{10}$ of the density squared integrated along the line of sight is plotted. The angles of rotation $(\theta ,\phi )$ for each image are shown in the lower right corner, with $\theta$ and $\phi$ the usual spherical coordinate angles. Those parts of the disk that are not yet being swept up by the wind are filtered out.

$\begin{figure} \par\includegraphics[width=17cm,clip]{1971fig7.eps} \end{figure}$ Figure 7: Grey scale plots of the synthesized position-velocity diagrams corresponding to the $\mbox{H}\alpha$ images of Fig. 6. Velocity is plotted along the horizontal axis and ranges from -33 to $+33~{\rm km}~\mbox{s}^{-1}$ . Position is plotted along the vertical axis and ranges from 0 to $334~{\rm AU}$ . The grey scale represents the $\log_{10}$ of the flux, (inverted; darker shades represent higher emission rates). All diagrams were convolved with a two-dimensional Gaussian with a FWHM of $10~{\rm km}~\mbox{s}^{-1}$ along the velocity axis, and a FWHM of $0\hbox{$.\!\!^{\prime\prime}$ }05$ along the position axis.
