J2102-4145 shows one 0.375-solar-mass white dwarf retaining a thick hydrogen envelope via stable mass transfer and a 0.314-solar-mass companion with an extremely thin envelope below 10^{-7} solar masses after common-envelope ejection, challenging standard bifurcation criteria.

Extreme mass loss during common envelope evolution: the origin of the double low-mass white dwarf system J2102--4145
J2102-4145 shows one 0.375-solar-mass white dwarf retaining a thick hydrogen envelope via stable mass transfer and a 0.314-solar-mass companion with an extremely thin envelope below 10^{-7} solar masses after common-envelope ejection, challenging standard bifurcation criteria.

The A Supergiant Eclipsing Binary BM Cas: An Evolved, Intermediate Mass System
BM Cas is an evolved Algol or post-Algol system in which the A supergiant primary fills its Roche lobe and the undetected secondary may be more massive, with the stars having had intermediate initial masses.
