The direct collision of asteroid-size bodies with a neutron star has been studied by one-dimensional hydrodynamic calculations with radiation diffusion. Gravitational energy is efficiently converted to thermal energy; very high temperatures at the contact point are produced on short time scales. Gamma-ray bursts of observed durations may result from the superposition of many short events from a tidally disrupted parent body. Spectral variation may occur as the temperature evolves and the form of the emitting region varies; the composite time-averaged spectrum need not resemble a blackbody. Long-term periodicity as observed for the Mar. 5, 1979 event (approximately 8 s) can result from the continuing deposition of remnant or preexisting material on the magnetic poles of an oblique rotator subsequent to the primary event in which the bulk of the material is deposited onto the polar caps of the neutron star. The probability of occurrence of such collisions is discussed.
