The Tidal Evolution of Local Group Dwarf Spheroidals

Abstract

We use N-body simulations to study the evolution of dwarf spheroidal galaxies (dSphs) driven by galactic tides. We adopt a cosmologically-motivated model where dSphs are dark matter-dominated systems on eccentric orbits whose stellar component may be approximated by a King model embedded within an NFW halo. We find that these NFW-embedded King models are… (More)
