标题： The Spherical Relativistic Detonation of Scalaron Stars

摘要： 目前，关于现代宇宙中存在各种性质和能量密度标量场的存在假设正在被深入研究。 它可以解释宇宙中暗（非重子）物质的本质以及正的$\Lambda $-项的存在（参见例如 gr-qc/9904398）。 这类场的一个分量具有团块性质，并且可以形成从星系尺度到相对论微观恒星的闭合引力结构。 在作者的论文 astro-ph/0008334 中考虑了此类场爆炸的假设。 相变波前之后会形成高能密度的相对论等离子体。 这一过程类似于相对论爆炸，并且能够产生足够的宏观火球来解释伽马射线暴现象（参见例如综述 astro-ph/9907392）。 在 astro-ph/0008334 中假定这种“爆炸”波前是由具有恒定能量密度的标量场流驱动的。 如果形成的等离子体结构的尺寸与标量子团簇的尺寸相当，则此假设并不正确。 有必要考虑标量场能量密度从中心到边缘的变化。 这从根本上改变了火球的动力学特性。 本文在狭义相对论框架内讨论了上述问题。 显示英文摘要

摘要： Now the hypothesis of existence of scalar fields of a various nature and energy density in the modern Universe is intensively explored. It can explain a nature of the dark (non- baryon) matter in the Universe and an existence of positive $\Lambda $-term (see e.g. gr-qc/9904398). One of component of such field has a cluster nature and organizes in the closed gravitational configurations from galactic scales up to relativistic microscopic stars. In the authors paper astro-ph/0008334 the hypothesis of detonation of such fields was considered. As a result of phase transition behind the wavefront a relativistic plasma of high energy density can appear. This process is similar to a relativistic detonation and it can create macroscopic fireballs sufficient for an explanation of the phenomenon of gamma-ray bursts (see e.g. the review astro-ph/9907392). In astro-ph/0008334 it was supposed that the front of such ''detonation'' wave is entered by the flow of scalar fields with constant energy density. If the size of the formed plasma configuration is commensurable with the size of scalaron cluster, this hypothesis is not correct. It is necessary to take into account a modification of the energy density of the scalar field from centre to a periphery. It is changes the dynamics of the fireball on principle. The indicated problem in framework of special relativity is considered in this paper.
