Description
The paper presents simulations of the outburst of U Sco by accreting material, with a solar abundance of the CNO nuclei, at a rate of 1.1 x 10 to the -6th solar mass/yr onto a 1.35-solar mass white dwarf. This evolutionary sequence takes about 2.6 yr to reach runaway conditions and ultimately eject 4 x 10 to the -7th solar mass moving with speeds exceeding about 400 km/s. It is found that ejection occurred by radiation pressure rather than by explosive CNO burning. 22 references
