毫秒脉冲星双星中存在的低质量、简并次星提供了一个机会，可以独立于脉冲星的旋转特性来确定双星系统的年龄。为此，我们在此详细计算了低质量（< 0.05 M⊙）氦核白矮星网格的演化过程。我们研究了不同氢层质量的影响，并提供了众所周知的光学带通的结果。我们用自己的低有效温度（Teff < 6000 K）计算补充了OPAL不透明度计算，并提供了重力作为质量和有效温度函数的拟合公式。在论文II中，我们将这些结果应用于个别情况。
The presence of low-mass, degenerate secondaries in millisecond pulsar binaries offers the opportunity to determine an age for the binary system independently of the rotational properties of the pulsar. To this end, we present here a detailed calculation of the evolution of a grid of low-mass (< 0.05 M⊙) helium core white dwarfs. We investigate the effects of different hydrogen layer masses and provide results for well-known optical bandpasses. We supplement the OPAL opacity calculations with our own calculations for low effective temperatures (Teff < 6000 K) and also provide fitting formulae for the gravity as a function of mass and effective temperature. In Paper II we apply these results to individual cases.
