Equation of state plotted in temperature as a function of gas number density, as listed in Table 1. Either the isothermal bulk temperature, T₀ (solid curves), or the polytropic index, γ₀ (dashed curves), is varied. The varied parameter and the corresponding run label are shown in the legend. With the purpose to understand the effects of temperature in low-density gas on the fragmentation outcome, the high-density end of all EOS is chosen to coincide.
