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.

Catastrophic disruption of differentiated asteroids creates a sheet-like mix of core and mantle fragments with uniform iron-rock ratios that reaccumulate into iron-rich rubble piles if the core is molten.
No clear hydroacoustic signals from 30 selected fireballs were detected across 53 station pairs, yielding a conditional upper limit on coupling efficiency of 10^{-10} and showing such detections are very rare.
Spectroscopic observations of disintegrating comet C/2019 Y4 (ATLAS) classify it as a typical Oort cloud comet with less dust, where porous dust accounts for its slightly red reflectivity gradient of ~5% per 1000 Å.

Consistency between dynamical modeling and photometrically derived masses of fireballs
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.
