.. _physics-satelliteEvaporationSIDM:

Dark Matter Self-interaction Satellite Evaporation
==================================================

Class providing models of the evaporation of orbiting satellites due to dark matter self-interactions (SIDM)---the mass loss from satellite halos caused by energetic scattering events between satellite dark matter particles and those of the host halo. High-momentum-transfer scatters can eject satellite particles, gradually eroding the subhalo on top of tidal stripping. Implementations return the satellite mass loss rate (in :math:`\mathrm{M}_\odot` Gyr\ :math:`^{-1}`) from SIDM-driven evaporation, which depends on the self-interaction cross-section, the satellite-host relative velocity, and the local number density of host particles.

**Default implementation:** ``satelliteEvaporationSIDMKummer2018``

Methods
-------

``massLossRate`` → ``double precision``
   Returns the satellite mass loss rate due to dark matter self-interactions (in units of :math:`\mathrm{M}_\odot`/Gyr).
