Johnson & Weinberg (2020), MNRAS, 498, 1364 Nucleosynthetic Yield Settings

Signature: from vice.yields.presets import JW20

New in version 1.1.0.

Importing this module sets the yields of oxygen, iron, and strontium to that adopted in the Johnson & Weinberg (2020) paper on starburst scenarios.

Note

This module is not imported with a simple “import vice” statement.

CCSNe

  • \(y_\text{O}^\text{CC}\) = 0.015

  • \(y_\text{Fe}^\text{CC}\) = 0.0012

  • \(y_\text{Sr}^\text{CC} = 3.5\times10^{-8}\)

SNe Ia

  • \(y_\text{O}^\text{Ia}\) = 0

  • \(y_\text{Fe}^\text{Ia}\) = 0.0017

  • \(y_\text{Sr}^\text{Ia}\) = 0

AGB

All three elements described by the Cristallo et al. (2011) [1] yields.
