Abstract

The possibility of existence of carbon-rich-planets makes it important to study High Energy States of carbon in order to understand the internal structure of such planets. In this paper, we present two-dimensional hydrodynamic simulations of a low-entropy compression of a carbon sample that is enclosed in a high-Z cylindrical shell that is driven by a high intensity uranium beam. The considered beam parameters are the ones that will be available at the accelerator facility, named, FAIR, at Darmstadt. This study has shown that the carbon sample can be compressed to 2 to 3 times solid density and ultra-high pressures are achieved. The temperature, on the other hand, remains relatively low. These are the typical physical conditions that are expected to exist in the planetary interiors. An experimental study of the thermophysical and transport properties of such samples will significantly improve our knowledge about formation and evolution of different type of planets.

在反质子和离子研究设施中使用强重离子束在极端物理条件下生产碳样品：在行星物理研究中的应用

富碳行星存在的可能性使得研究碳的高能态以了解这类行星的内部结构变得非常重要。在本文中，我们提出了低熵压缩碳样品的二维流体动力学模拟，该碳样品被封闭在高z圆柱壳中，由高强度铀束驱动。所考虑的光束参数将在达姆施塔特名为FAIR的加速器设施中使用。这项研究表明，碳样品可以被压缩到固体密度的2到3倍，并且可以实现超高压。另一方面，气温仍然相对较低。这些是预期存在于行星内部的典型物理条件。对这些样品的热物理和输运性质的实验研究将大大提高我们对不同类型行星形成和演化的认识。
