RHSolver

Overview

This entry contains all relevant settings for running cooling simulation with rotochemical heating [FR05].

Description

• "TimeUnits" (double, [RH]) : Conversion factor from time to natural units (GeV powers). It must either be supplied as a choice from [“Gev-1”, “S”, “Yr”, “Ms”], or as an actual multiplier. Used for “RotationalOmegaSquareDot” parameters.

• "RotationalOmegaSquareDot" (array, [RH]) : Rotational frequency settings. The first element is a string with mode, while the others denote parameters for this mode.

Note

The only supported mode is “BeyondMagneticDipole”, which is described in [Yan20] (Eq. 2.102) and is given by

\[ \Omega(t) = \dfrac{2\pi}{P_0}\left(1 + \dfrac{(n-1)\dot P_0}{P_0}t\right)^{-\frac{1}{n-1}}. \]

We denote \([n, P_0, \dot P_0]\) via array[1-3]. \(P_0\) is measured in “TimeUnits”.
