Luminous Supersoft X-Ray Sources as Progenitors of Type Ia Supernovae

  title={Luminous Supersoft X-Ray Sources as Progenitors of Type Ia Supernovae},
  author={Rosanne Di Stefano},
In some luminous supersoft X-ray sources, hydrogen accretes onto the surface of a white dwarf at rates more-or-less compatible with steady nuclear burning. The white dwarfs in these systems therefore have a good chance to grow in mass. Here we review what is known about the rate of Type Ia supernovae that may be associated with SSSs. Observable consequences of the conjecture that SSSs can be progenitors of Type Ia supernovae are also discussed.
