Can bars be destroyed by a central mass concentration? I. Simulations
E. Athanassoula, J. C. Lambert, W. Dehnen
We study the effect of a central mass concentration (CMC) on the secular evolution of a barred disc galaxy. Unlike previous studies, we use fully self-consistent 3D -body simula…
Relaxation times calculated from angular deflections
E. Athanassoula, Ch. L. Vozikis, J. C. Lambert
In this paper we measure the two-body relaxation time from the angular deflection of test particles launched in a rigid configuration of field particles. We find that centrally con…
Optimal softening for force calculations in collisionless N-body simulations
E. Athanassoula, E. Fady, J. -C. Lambert +1
In N-body simulations the force calculated between particles representing a given mass distribution is usually softened, to diminish the effect of graininess. In this paper we stud…
Performance and accuracy of a GRAPE-3 system for collisionless N-body simulations
E. Athanassoula, A. Bosma, J. -C. Lambert +1
The performance and accuracy of a GRAPE-3 system for collisionless N-body simulations is discussed. After a description of the hardware configurations available to us at Marseille,…
