The Formation of Low-Mass Double White Dwarfs through an Initial Phase of Stable Non-Conservative Mass Transfer
Although many double white dwarfs (DWDs) have been observed, the evolutionary channel by which they are formed from lowâmass/longâperiod redâgiantâmainâsequence (RGâMS) binaries remains uncertain. The canonical explanations involve some variant of double commonâenvelope (CE) evolution, however it has been found that such a mechanism cannot produce the observed distribution. We âŚ
