Moe, Kratter & Badenes (2019) - progenax — differentiable initial conditions for N-body simulations

Abstract (paraphrased)¶

The close-binary fraction of solar-type stars varies strongly with metallicity, from $\sim 53\%$ at $\mathrm{[Fe/H]} = -3$ to $\sim 10\%$ at $\mathrm{[Fe/H]} = +0.5$ . Important for binary population synthesis at low metallicity.

Use in progenax¶

Binary-aware IMF recovery — metallicity caveat on Moe17 calibration
Multiplicity statistics (Moe & Di Stefano 2017) — metallicity dependence note

Notes¶

Important caveat to Moe & Di Stefano (2017) for low-metallicity populations.
