Prša et al. (2016) - progenax — differentiable initial conditions for N-body simulations

What it provides¶

IAU 2015 Resolution B3 fixes a set of nominal conversion constants so that solar and planetary quantities are reported against exact, agreed reference values — decoupling them from the slowly-improving measured constants. The quantity progenax depends on is the nominal solar mass parameter,

(\mathcal{GM})_\odot^{\mathrm N} = 1.3271244\times10^{20}\ \mathrm{m^3\,s^{-2}},

(1)

reported alongside nominal solar radius, luminosity, and effective temperature, and the analogous nominal terrestrial and Jovian quantities.

Use in progenax¶

progenax.analytical.base — the solar-mass unit underlying SOLAR_SYSTEM_PLANETS is this IAU 2015 nominal mass parameter. (The planet/Sun mass ratios in that table are IAU 2009 / Luzum et al. 2011, verified separately — see Analytical test cases validation.)
