Non-isotropic clumping can also favor
ÒsidewaysÓ escape, and thus suppression of the bluest and reddest
photons, if the clumps are oblate.This makes lines more symmetric.
The Venetian
Blind Model...
Oblate clumps might be
expected from the line-force instability, since it is a radial forceÉ
On the other hand, prolate
structures might be expected to develop from classical plasma two-fluid
instabilities (Rayleigh-Taylor; Richtmeyer-Meshkov)
