P. ; Shapiro, S. L. ; Wasserman, I. Abstract It is shown that the gravitational radiation emitted in a head-on collision between a finite-size star and a black hole can be substantially less than might be expected on the basis of results for point mass-black hole collisions. The suppression 'form factor' for gravitational radiation from a dust cloud freely falling from rest at infinity into a Schwarzschild black hole of much greater mass is calculated. It is found that whenever the infalling star is tidally disrupted by the black hole prior to capture, the energy outflow in gravitational radiation may be much less than that for an infalling point particle of the same mass. This severe suppression results from phase incoherence in the outgoing radiation. Analytic expressions are derived for the total wave energy and wave amplitude in terms of the point-mass results. Head-on, free-fall collisions of main sequence, white dwarf, and neutron stars with black holes of different masses are considered.
