The Fate of a WD Accreting H-Rich Material at High Rates

The Fate of a WD Accreting H-Rich Material at High Rates

We study a white dwarf (WD) accreting solar-composition material at super-Eddington accretion rates. We find that after many cycles of hydrogen ignition and burning, several large Helium burning flashes expel the accreted envelope, leaving no net mass accumulation. This implies that such a system wi...

Zusammenfassung:We study a white dwarf (WD) accreting solar-composition material at super-Eddington accretion rates. We find that after many cycles of hydrogen ignition and burning, several large Helium burning flashes expel the accreted envelope, leaving no net mass accumulation. This implies that such a system will not undergo accretion induced collapse.
