A new three-point inverse solution using the α-β model reconstructs meteoroid masses and bulk densities from limited fireball observations, achieving 88% convergence on the EN catalog and producing a continuous density range of 300-4000 kg m^{-3} instead of discrete PE categories.
Hydrodynamical simulations of giant impacts find lower post-impact CMB pressures due to thermal and rotational effects, common full mantle melting, and conditions favoring metal-silicate equilibration near the CMB.
High-speed imaging of four lunar impact flashes reveals lower variance in initial intensity than total energy and no correlation between them, suggesting decoupled vapor and ejecta phases.
Numerical model of C outgassing shows CC planetesimals deplete >50% carbon while NCs deplete <50% for typical sizes and formation times, favoring NC bodies as the main C source for terrestrial planets.
An upgraded planet population synthesis model incorporates post-disc dynamical evolution and atmospheric enrichment to generate synthetic exoplanet populations with improved fidelity to N-body results and observations.
