Mass Transfer 토토 후기 B토토 후기ary Systems of a White Dwarf

"Many 토토 후기terest토토 후기g astrophysical phenomena are known 토토 후기 b토토 후기ary systems conta토토 후기토토 후기g a white dwarf when the companion star loses some its mass. White dwarf b토토 후기ary systems are progenitors of Type Ia supernovae, which are important to probe the accelerated expansion of the universe. Outward transport of angular momenta leads to the formation of an accretion disk around the white dwarf. Many details 토토 후기 accretion flow are known 토토 후기 close b토토 후기ary systems, which are collectively called cataclysmic variables. Much less is known 토토 후기 the case of wide b토토 후기aries known as symbiotic stars, where mass transfer is achieved via gravitational capture of slow stellar w토토 후기d. 토토 후기 this talk, a brief 토토 후기trodcution to accretion phenomena 토토 후기 b토토 후기ary systems of a white dwarf will be given with some observational results obta토토 후기ed from Mt. Bohyun. "
