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.
ZTF-discovered radial-mode sdB pulsators have mean Teff of 28,300 K and log g of 5.56, placing them at the boundary between V361 Hya and V1093 Her classes with canonical masses and distinguishing them from blue large-amplitude pulsators.
Direct O-C timing analysis yields an orbital decay rate of (-1.97 ± 0.05) × 10^{-12} s s^{-1} in ZTFJ2130, from which a chirp mass of 0.408 ± 0.006 solar masses is derived assuming pure GW emission.

Extreme mass loss during common envelope evolution: the origin of the double low-mass white dwarf system J2102--4145
