Nebular spectroscopy of low-luminosity Type IIP SNe from ZTF identifies two plausible ECSN candidates but derives an upper limit on the ECSN rate of ≲(5–8)×10² Gpc⁻³ yr⁻¹ implying a sAGB mass window narrower than 0.06 M⊙.

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.
