A cluster white-dwarf/M-dwarf binary with a 6.99-hour orbit provides the first precise pre/post-common-envelope benchmark, implying a 5.4-solar-mass progenitor and a common-envelope efficiency of either ≈0.99 (mid-AGB) or ≈0.05 (late-AGB).

Orbital solutions for 15 double-lined double white dwarf binaries, mostly with periods 12-75 hours, doubling the number of well-characterized compact DWDs at long periods.
Triple-star dynamics are a significant, previously neglected formation channel for cataclysmic variables, including a common-envelope-free route.
Two newly found eclipsing white dwarf plus brown dwarf binaries contain companions of about 20 Jupiter masses, extending known survivors of common envelope evolution far below the previous ~50 Jupiter mass limit.
Self-lensing signals occur with probabilities of roughly 10^{-3} in WD+NS systems and 10^{-2} in WD+BH systems; TESS could detect at least one if 8% of white dwarfs have NS companions and 3% have BH companions, while Roman cannot.
New catalog of white dwarfs from DESI DR1 spectra with parameters for DA types and 547 magnetic objects showing they are more massive and have fields before crystallization.
TESS photometry reveals periodic trends in six of seventeen double white dwarfs, with LP400-22 and J2132+0754 showing orbital-period and half-orbital-period variations.
On the same Gaia 40 parsec white dwarf sample, the luminosity function, absolute G magnitude distribution, and direct age methods give star formation histories that agree within systematic uncertainties.
