论文摘要

我们研究了温度和磁场在玻色子凝结物恒星状态和宏观特性方程方面的作用。这些紧凑的物体由相互作用的中性载体玻色子的冷凝气体组成,该载体与均匀且恒定的磁场结合。我们发现,在磁化状态方程中有限温度的主要结果是增加恒星的内部压力。结果,磁化热的玻璃晶冷凝液星星比零温对应物更大,重。但是,该模型获得的最大质量几乎保持不变,并且恒星的磁变形随温度而增加。此外,增加温度会减少稳定恒星的数量,从而使磁场增强的效果。还分析了我们结果对恒星进化,紧凑,红移和质量四极力矩的含义。

We study the role of temperature and magnetic field on the equation of state and macroscopic properties of Bose-Einstein condensate stars. These compact objects are composed of a condensed gas of interacting neutral vector bosons coupled to a uniform and constant magnetic field. We found that the main consequence of a finite temperature in the magnetized equations of state is to increase the inner pressure of the star. As a consequence, magnetized hot Bose-Einstein condensate stars are larger and heavier than their zero-temperature counterparts. However, the maximum masses obtained by the model remain almost unchanged, and the magnetic deformation of the star increases with the temperature. Besides, augmenting the temperature reduces the number of stable stars, an effect that the magnetic field enhances. The implications of our results for the star's evolution, compactness, redshift, and mass quadupolar moment are also analyzed.
