A rapidly-accreting white dwarf (RAWD) is a white dwarf that accretes matter from a companion star (illustrated), rapidly enough to steadily burn on its surface the accreted hydrogen into helium. Once a RAWD reaches a critical mass, the accumulated shell of helium undergoes a thermal flash that triggers convection.
