The hot Lattimer and Swesty (LS) EOS uses the liquid drop model for nuclei. It is harder than the cold, beta-equilibrium EOS above neutron drip (see below). The stiffening of the LS EOS increases the amount of parameter space available to fizzlers (Hayashi et al. 1998,1999) when compared to results found using the cold beta-equilibrium EOS.

The three curves are for the BPS EOS (dashed-dot line), and Y_e = 0.2 (dashed line)and 0.3 (solid line). The BPS EOS is softer at high density when compared to the LS hot EOSs. The two sets of curves are for S_b = 0.7 and 1.5 k. The BPS EOS shows the drop after 10¹¹ g cm^-3.



The LS EOS is very soft, however. For the relevant portions of parameter space, the effective polytropic index,

is n_eff = 2.5-3.5 (see below).

Axisymmetric radial instability occurs for n greater than or equal to 3.
