对ROSAT观测到的10个超软X射线源参数进行了分析，这些参数由覆盖近似和LTE模型大气得到。研究了所得参数与白矮星表面稳定燃烧/循环燃烧模型的一致性。其中七个源的亮度和大小与该模型符合得很好。估计了这些源中白矮星的质量。本文给出了一个根据白矮星的有效温度估算经典超软源中白矮星质量的公式。
The parameters of ten supersoft X-ray sources observed by ROSAT obtained using blanketing approximations and LTE model atmospheres are analyzed. The consistency of the resulting parameters with a model with stable/recurrent burning on the surface of the white dwarf is studied. The luminosity and sizes of seven of the sources are in good agreement with this model. The masses of the white dwarfs in these sources are estimated. A formula that can be used to estimate the masses of white dwarfs in classical supersoft sources based on their effective temperatures is presented.
