| 英文摘要: | We carried out numerical modeling of impacts of asteroids and icy bodies with a diameter from 30 m to 100 m and calculated radiation fluxes on the ground, luminous efficiencies and areas of potential fire. The integral luminous efficiency of impactors with a diameter of 30 m entering the atmosphere at acute angles can reach 20 and 40% for stony and icy bodies respectively, and the impacts of 100-m asteroids can initiate forest fires in areas with dimensions of 100 km. © 2018 Elsevier B.V. |
