POSYDON: Building Populations with Object-Oriented Design
POSYDON provide a fully customizable framework to population synthesis modeling. By leveraging the power and flexibility of object-oriented design, it offers a modular and scalable architecture that enables researchers to customize, extend, and integrate various astrophysical processes with ease. This section delves into the intricacies of the POSYDON hierarchy, outlining the key classes, their interrelationships, and their roles in crafting sophisticated population synthesis models.
The Single Star Object
The SingleStar object contains the stellar properties and its evolutionary history. The single star object is passed to the BinaryStar class to create a BinaryStar object.
The Binary Star Object
The BinaryStar object contains the binary properties and its evolutionary history as well as two SingleStar. The binary star object is passed to the BinaryPopulation class to create a population synthesis model.
The Binary Population Object
The BinaryPopulation object contains a list of BinaryStar objects and the SimulationProperties object which contains the information about the population synthesis model.
The Simulation Properties object
POSDYON Population Synthesis Configuration Guide
The SimulationProperties objects contains the POSYDON population synthesis parameter configurations determining the evolution of each binaries in the BinaryPopulation class. The following guide will walk you through the configuration parameters of a POSYDON binary population synthesis model.
The Flow Chart Object
The flow chart object is the main object that is used to configure the population synthesis model. It is a dictionary that contains all the parameters that are used to configure the model. The flow chart object is passed to the BinaryPopulation class to create a population synthesis model.
Evolutionary Hooks
The evolutionary hooks allows the use to execute code between POSYDON steps. The following guide will walk you through the evolutionary hooks that are available in POSYDON.
The Synthetic Population Object
The SyntheticPopulation object contains a collection of BinaryPopulation objects run, e.g. at different metallicities or with different model assumptions. It also provide the POSYDON API interface to analyse, process, and visualize the results of a POSYDON population synthesis model.
Debugging POSYDON population synthesis models
POSYDON provides a set of tools to debug population synthesis models. The following guide will walk you through the debugging tools that are available in POSYDON.
