论文摘要
目前的工作涉及辐射恒星的动力学，该动力学被认为是膨胀的无圆柱对称性粉尘耗散流体。用于描述此类恒星的几何和物理特征的描述，采用了几种治疗方法。首先，可以表明，动态恒星不允许流出的极限和扩散近似，还证明加速度和耗散是其动力学演化所必需的。它还表明，静态膨胀缸必须不辐射。其次，还研究了这种动力恒星的腔模型和自相似解的存在。
The present work deals with the dynamics of radiating star which is considered to be expansion free cylindrical symmetric dust dissipative fluids. Several treatments are adopted for the description of geometrical and physical features of such stars. Firstly, it is shown that, the dynamical star does not permit the streaming out limit and diffusion approximation and also proved that acceleration and dissipation are necessary for its dynamical evolution. It has also shown that, a static expansion free cylinder must be non-radiating. Secondly, the existence of cavity model and self-similar solution for the such dynamical star are also investigated.
