| Outline of Final Research Achievements |
The purpose of this research is to verify the mass limit of white dwarfs by measuring masses and radii of white dwarfs. The absolute luminosity of any type Ia supernova is thought to be almost constant because the mass limit is believed to be constant for any white dwarfs. Therefore, type Ia supernovae are used to measure distance to distant galaxies.
To accomplish the purpose, I created an X-ray spectral model of white dwarfs. Especially, I note that I modeled spectrum of X-ray reflection from white dwarf surface by a detailed computer simulation in addition to thermal X-ray spectrum from plasma near the white dwarf surface. The purpose will be accomplished by application of my X-ray spectral model to observed data.
