“Speeding Young Star”(The Moment)

Animation for Good, and for Ill

Good

Stories (a.k.a.) “Visual Explanations”

Evolution of processes in time“Tracking”Finding key moments

Ill

Studying processes where non-sequential frames are critically related

e.g. 2-D slices of 3-D data, shown in time

Numerical Simulation of Star Formation (Good)

Bate, Bonnell & Bromm 2002 (UKAFF)

•MHD turbulence gives “t=0” conditions; Jeans mass=1 Msun

•50 Msun, 0.38 pc, navg=3 x 105 ptcls/cc

•forms ~50 objects

•T=10 K

•SPH, no B or •movie=1.4 free-fall times

QuickTime™ and aCinepak decompressor

are needed to see this picture.
