About spindler

A python package to compute the long-term orbital evolution of a binary interacting with a circumbinary disk, based on Valli et al. 2024 (https://doi.org/10.48550/arXiv.2401.17355)

Models

spindler provides three alternative models of binary-disk interaction

• Siwek23: based on the simulations in

  • Siwek et al. 2023 (2023MNRAS.518.5059S)

  • Siwek et al. 2023 (2023MNRAS.522.2707S)

  It is defined for eccentricity between 0 and 0.8, and mass ratio between 0.1 and 1.

• DD21: based on the simulations in

  • D’Orazio and Duffell 2021 (2021ApJ…914L..21D)

  It is defined for eccentricity between 0 and 0.8, and mass ratio equal to 1.

• Zrake21: based on the simulations in

  • Zrake et al. 2021 (2021ApJ…909L..13Z)

  It is defined for eccentricity between 0 and 0.8, and mass ratio equal to 1.
