The Fate of Gas rich Satellites in Clusters
  We investigate the stellar mass loss of gas rich galaxies falling into
clusters due to the change in the gravitational potential caused by the ram
pressure stripping of their gas. We model the satellites with exponential
stellar and gas disk profiles, assume rapid ram pressure stripping, and follow
the stellar orbits in the shocked potential. Due to the change of the
potential, the stars move from circular orbits to elliptical orbits with
apocenters that are often outside the tidal radius, causing those stars to be
stripped. We explore the impact of the redshift of infall, gas fraction,
satellite halo mass and cluster mass on this process. The puffing of the
satellites makes them appear as ultra diffuse galaxies, and the stripped stars
contribute to the intracluster light. Our results show these effects are most
significant for less-massive satellites, which have larger gas fractions when
they are accreted into clusters. The preferential destruction of low mass
systems causes the red fraction of cluster galaxies to be smaller at lower
masses, an observation that is otherwise difficult to explain.
