Four solar-type twin binaries show evolutionary diversity from main-sequence to red-giant stages with varying magnetic activity, including possible triple-system signatures in one case.
An ensemble ML framework achieves 90.7% morphology classification accuracy and R² values of 0.77–0.92 for key parameters on held-out test data, with external validation against OGLE and Kepler catalogs.
