The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.

sirf: self-irradiated funnel

The multi-blackbody “Self-IrRadiated Funnel” model is designed to model optically-thick outflow-dominated accretion. The basic idea is simple: you just assume a lot of matter, angular momentum and energy emerges in a limited volume. Momentum conservation leads to non-sphericity of the flow that has subsequently conical (funnel-like) shape. The model calculates temperature distribution at the funnel walls (taking into account irradiation by iterative process) and the outer photosphere. We also assume that inside the cone there is a deep pseudo-photosphere. Relativistic boosts are taken into account for high velocities. For a comprehensive description of the physical model, see: Abolmasov, Karpov & Kotani (2009).

par1 $t_{in}$, inner temperature (at the inner, inside-the-funnel photosphere).
par2 $r_{in}$, inner (inside-the-funnel photosphere) radius in “spherisation radius” units (the latter is defined as $3K\dot{M}/\Omega_fc$).
par3 $r_{out}$, outer photosphere radius in “spherisation radius” units.
par4 $\theta$, half-opening angle of the cone.
par5 incl, inclination angle of the funnel. Affects mainly self-occultation and relativistic boost effects.
par6 $v_\alpha$, velocity law exponent, $v \propto r^{v_\alpha}$.
par7 $\gamma$, adiabatic index. It affects the inner, hotter parts of the flow, therefore we set is to 4/3 by default.
par8 $\dot{m}$, mass ejection rate in Eddington (critical) units.
par9 irrad, number of iterations for irradiation.
