The Vega equation of state for hard (biaxial) ellipsoids is given by (Ref. 1 Eq. 20):
where is the compressibility factor and is the volume fraction, given by
where is the number density.
The virial coefficients are given by the fits
and
where
- ,
and
where is
the volume, , the surface area, and the mean radius of curvature.
For see B_2 for any hard convex body.
