奇异矮星
Strangelet dwarfs
摘要:
如果夸克物质的表面张力足够低,夸克物质就不会自束缚。在足够低的压力和温度下,它将在电子的中和背景下以带正电的奇异晶体的形式存在。在这种情况下,除了通常的奇异星家族之外,还存在一个类似于白矮星的低质量大半径天体家族,我们称之为“奇异矮星”。利用夸克物质状态方程的一般参数化,我们计算了这些物体的质量-半径关系。
英文摘要:
If the surface tension of quark matter is low enough, quark matter is not self bound. At sufficiently low pressure and temperature, it will take the form of a crystal of positively charged strangelets in a neutralizing background of electrons. In this case there will exist, in addition to the usual family of strange stars, a family of low-mass large-radius objects analogous to white dwarfs, which we call "strangelet dwarfs". Using a generic parametrization of the equation of state of quark matter, we calculate the mass-radius relationship of these objects.
