Axisymmetric two-dimensional calculations follow gas confined by a dark halo as the galaxy moves through a hot cluster atmosphere.
Main result
Typical cluster conditions in the models remove the halo’s gas. Environmental stripping therefore strongly affects the subsequent chemical evolution of these dwarfs.
Scientific implications
The result links gas-poor cluster satellites to their environment and motivates early enrichment before cluster virialization.
Scope and limitations
The outcome depends on the assumed atmosphere, galaxy structure and motion. These idealized calculations do not imply that every cluster dwarf loses gas on the same schedule.
