论文摘要

白色矮星的简单冷却模型在Palatini $ f(r)$ gravity中重新分析。修饰的重力会影响白矮结构,因此会影响其年龄。我们发现,与牛顿型模型相比,所得的超级chandrasekhar白矮人需要更多的时间来冷却。

A simple cooling model of white dwarf stars is re-analyzed in Palatini $f(R)$ gravity. Modified gravity affects the white dwarf structures and consequently their ages. We find that the resulting super-Chandrasekhar white dwarfs need more time to cool down than sub-Chandrasekhar ones, or when compared to the Newtonian models.
