标题： Mass-radius relations for massive white dwarf stars

摘要： 我们提出了具有氧-氖核心的高质白矮星的详细理论质量-半径关系。 这项工作是受到最近关于存在极高表面重力白矮星的观测证据的启发。 我们的结果基于考虑了大质量白矮星前体演化历史预期的化学组成的演化计算。 我们给出了从1.06到1.30 Mo，步长为0.02 Mo的恒星质量值以及从150000 K到约5,000 K的有效温度范围内的理论质量-半径关系。 我们的计算预测的一个新方面是，最重的白矮星的质量-半径关系明显依赖于中微子光度。 还提供了可从我们的网站访问的大质量白矮星的详细表格。 显示英文摘要

摘要： We present detailed theoretical mass-radius relations for massive white dwarf stars with oxygen-neon cores. This work is motivated by recent observational evidence about the existence of white dwarf stars with very high surface gravities. Our results are based on evolutionary calculations that take into account the chemical composition expected from the evolutionary history of massive white dwarf progenitors. We present theoretical mass-radius relations for stellar mass values ranging from 1.06 to 1.30 Mo with a step of 0.02 Mo and effective temperatures from 150000 K to approx. 5,000 K. A novel aspect predicted by our calculations is that the mass-radius relation for the most massive white dwarfs exhibits a marked dependence on the neutrino luminosity. Extensive tabulations for massive white dwarfs, accessible from our web site, are presented as well.
