Analytic Solutions for Truncated Plasmons
ABSTRACT We present a new plasmon model for a cometary clump moving supersonically in an environment with a non-zero gas pressure. We find that the environmental pressure produces a cutoff in the wings of the cometary clump, therefore resulting in quite \stubby" plasmons for a large range of ow Mach numbers. We derive a relation between the length-to-width ratio of the plasmon and the Mach number M of the ow, which could be used to directly derive M from observations of (appropriate) cometary clumps.
