We present N-body simulations of elliptical galaxy encounters into dry mergers to study the resulting unbound intergalactic stellar population, in particular that of the post-main-sequence stars. The systems studied are pairs of spherical galaxies without dark halos. The stellar content of the model galaxies is distributed into mass bins representing low- and intermediate-mass stars (0.85-8 M☉) according to the Salpeter initial mass function. Our models follow the dynamical evolution of galaxy… Expand
