论文摘要
在本文中，我们提出了$ f（\ mathbb {t}）$重力下的恒星模型。 Proc。纳特。学院。科学。美国101（2004）9545]在文献中被称为{\ it grastar}，这是黑洞的可行替代品。该Grastar具有三个不同的区域，即（a）内部核心区域，（b）中间薄壳和（c）外部球形区域。假定在内部区域，流体压力等于负物质能量密度，从而在球形薄壳上提供了恒定的排斥力。假定该中间区域的壳是由超层析等离子体的流体和压力形成的，根据Zeldovich的猜想，与物质能量密度成正比，这是直接成正比的。不是。 R. Astron。 Soc。 160（1972）1]，确实使内部核心区域施加的排斥力无效，以进行稳定的配置。另一方面，外部球形区域可以通过外部Schwarzschild-De保姆解决方案来描述。有了所有这些规格，我们发现了一组精确的和奇异性的解决方案，该解决方案在替代引力的框架内提出了几种物理上有趣的和有效的特征。
In the present paper we propose a stellar model under the $f(\mathbb{T})$ gravity following the conjecture of Mazur-Mottola~[Report number: LA-UR-01-5067 (2001); Proc. Natl. Acad. Sci. USA 101 (2004) 9545] known in literature as {\it gravastar}, a viable alternative to the black hole. This gravastar has three different regions, viz., (A) Interior core region, (B) Intermediate thin shell, and (C) Exterior spherical region. It is assumed that in the interior region the fluid pressure is equal to a negative matter-energy density providing a constant repulsive force over the spherical thin shell. This shell at the intermediate region is assumed to be formed by a fluid of ultrarelativistic plasma and the pressure, which is directly proportional to the matter-energy density according to Zeldovich's conjecture of stiff fluid~[Zeldovich, Mon. Not. R. Astron. Soc. 160 (1972) 1], does nullify the repulsive force exerted by the interior core region for a stable configuration. On the other hand, the exterior spherical region can be described by the exterior Schwarzschild-de Sitter solution. With all these specifications we have found out a set of exact and singularity-free solutions of the gravastar which presents several physically interesting as well as valid features within the framework of alternative gravity.
