| 摘 要： | 研究了有限温度条件下分别由Fe核和C核构成的热白矮星.结果表明随着温度升高,对应同一质量的白矮星的半径增加.温度对白矮星质量-半径关系的影响强度随着星体质量的增加而减弱.相比于Fe-白矮星,C-白矮星的质量-半径关系对温度的依赖程度较大.存在一个临界质量,当白矮星的质量小于这个临界值时,温度的影响将不能忽略.C-白矮星...

| Abstract: | The Fe - core and C - core thermal white dwarfs under finite temperature are studied with the result that the radius of dwarfs with the same mass will be longer with the increase of temperature,and the temperature will be lower with the increase of mass.Compared to Fe - core white dwarfs,C - core dwarfs depend to a greater degree on temperature for the relationship between mass and radius.There exists a critical mass. When white dwarfs,mass is less than the critical mass,the effect of temperature to the rel... |
