SNART: Synchrotron Self Absorption Model For Non-relativistic Transients.

DEMARCHI L., FINSTAD D. and MARGUTTI R.

Abstract (from CDS):

We present SNART (DeMarchi & Finstad ), software for radio synchrotron self-absorption analysis, a generalized version of the model introduced in Chevalier, Chevalier & Fransson. SNART ingests flux density and frequency observations, fits them jointly, and outputs system physical parameters: magnetic field B, shock radius R, post shock energy U, electron number density ne, circumstellar density ρCSM, and mass loss degenerate with wind velocity $\dot{M}/{v}_{\mathrm{wind}}$. SNART is written in Python and is publicly available via GitHub. The repository hosts an in-depth derivation of the model and a detailed description of parameter definitions in the literature. SNART is a generalized treatment of synchrotron self absorption that leaves the choice of values for p (the power-law index of the electron distribution), q (shock front acceleration), θ (electron pitch angle, commonly π/2), and f (the “filling factor,” often 0.5) explicit.
