Abstracthooray!

## Introduction

This is new!

Colella and Glaz (1985)11This is a test

## Numerical Experiments

• Could try not tracing the $$\gamma_{e}$$. First order in time approach.

• Zingale & Katz with UHD. Both with Helmholtz and Nuclear. But Nuclear doesn’t go down so low…

• do Helmholtz at high density/temperature in range of Nuclear. Will need to determine the appropriate $$\sum Y_{i}$$. Might be able to determine this from data in the table. If $$\bar{A}$$ and $$\bar{Z}$$ are available…

• Should also try ”EOSforRiemann” approach.

• Need to address construction of wave speeds in HLLC for general EOS (Zingale and Katz, 2015)
