Overview

redback-csm provides Fortran-based circumstellar matter (CSM) interaction models for use with the redback transient inference package. Once installed, all CSM models are automatically discovered and available in redback.model_library.all_models_dict.

The package also includes redback_csm.explore.csm_lightcurve_from_density(), a standalone utility for computing and plotting light curves from an arbitrary user-supplied ρ(r) profile (e.g. from stellar-evolution codes) — useful for exploration and visualisation without Bayesian inference.
