Detection of 17.26-day eclipses in KQ Puppis reveals it as a hierarchical triple with dynamical masses of ~10 M⊙ for the RSG and ~14 M⊙ for the inner pair, plus the first orbital parallax for any red supergiant.

Failed common envelope mergers yield 6-14 solar mass stripped stars consistent with long-lived core He-burning objects that appear single or in wide binaries from hierarchical triples.
Binary population synthesis predicts several thousand intermediate-mass helium stars in the Milky Way, mostly in binaries, with metallicity and common-envelope ejection efficiency as the dominant shaping factors.
Natal kicks from supernovae are proposed to disrupt Gaia progenitor binaries containing low-mass black holes more frequently than those leading to gravitational-wave mergers, accounting for the observed difference in the 2.5-5 solar mass gap.
