Simulations of giant impacts between 0.2-4 Earth-mass planets yield post-impact luminosities of 5e-5 to 0.1 L_sun cooling over 1-2000 days, predicting 0-14 detections in Gaia DR4 and a comparable number in LSST.
A review of SPH modeling for global-scale impacts, emphasizing material properties across size regimes and links to Solar System observations.
