SPICE is a JAX-based framework for simulating stellar spectra that includes stellar surface inhomogeneities, such as spots, temperature gradients, pulsations, and binary effects.

The software combines a machine-learning model Transformer Payne (Różański et al., 2024) with a 3D stellar mesh system to efficiently model complex surface phenomena. Key features include:

• Comprehensive Modeling: Simulates spots, temperature gradients, pulsations, and binary effects.
• Integration: Seamlessly integrates with the PHOEBE binary modeling framework.
• Flexibility: Offers customizable spectral grids and surface properties.
• Differentiable Pipeline: Enables gradient-based inference methods and ML approaches for parameter estimation.

Please reach out if you have any ideas or suggestions, as well as feature requests! I am happy to include more features, as well as help you integrate SPICE into your research. We can also discuss creating custom spectral models for your needs.
