Synthetic observables from tECSN models show slower early red-color decline due to higher Ti/Cr and a late-time 12.8 μm Ne II line that strengthens over time, unlike comparable CO deflagration models.

Type Ib supernovae are systematically bluer than Type Ic supernovae in optical colors, likely due to helium-rich versus helium-poor progenitors.
Milky Way abundance trends act as effective empirical proxies for nucleosynthetic yields, recovering alpha and Fe-peak abundances in quiescent galaxies with 0.05 dex median offset versus 0.23 dex for theory, indicating largely universal yields.
Interstellar objects may contribute enough baryonic mass to reduce the local dark matter halo density to 0.24 GeV/cm³.
Age dating of R127 and R128 clusters shows the brightest stars are peculiar relative to single-star models, with implications for binary-driven LBV evolution.
