Descripción
We present the 2-D, two fluid (ions + neutrals) numerical simulations
that we are carrying out in order to study the ambipolar filamentation
process, in which a magnetized, partially ionized plasma is stirred by
turbulence in the ambipolar frequency range. The higher turbulent
velocity of the neutrals in the most ionized regions gives rise to a
non-linear force driving them out of these regions, and causes the ions
and the magnetic flux to condense in the most ionized regions, resulting
in a filamentary structure where initial ionization inhomogeneities are
amplified. This mechanism might help to explain some features observed
in magnetized and partially ionized astrophysical plasmas as the
interstellar medium.
