Stellar Population Synthesis Modeling

SPISEA: Stellar Population Interface for Stellar Evolution and Atmospheres

SPISEA is an python package that generates single-age, single-metallicity populations (i.e. star clusters). It gives the user control over many parameters:

• Cluster characteristics (age, metallicity, mass, distance)
• Total extinction, differential extinction, and extinction law
• Stellar evolution and atmosphere models
• Stellar multiplicity and Initial Mass Function
• Initial-Final Mass Relation
• Photometric filters

Here is a brief list of things that SPISEA can do:

• make a cluster isochrone in many filters using different stellar models
• make a star cluster at any age with an unusual IMF and unresolved multiplicity
• make a spectrum of a star cluster in integrated light

See documentation for details on installing and running SPISEA. We also provide jupyter notebooks with a quick-start tutorial and additional examples demonstrating how to use SPISEA.

If you use SPISEA in your research, please cite Hosek et al. (2020).

Change Log

SPISEA is actively supported and is growing in functionality, and subsequently has had several updates since its initial release. See the main documentation page for the change log describing the updates in each release.

Contributions

We welcome and encourage contributions to SPISEA! For feature additions, we ask that users make their own fork of the repository, make their changes, and then submit a pull request to the "dev" branch.

All contributions will be acknowledged on the contributors page (with permission). Contributors with features used in code releases will be co-authors in future SPISEA software papers.
