Work in progress, 0.0.3-beta released

spotter

Forward models of non-uniform stellar photospheres and their spectra

spotter is a Python package to produce forward models of non-uniform stellar photospheres and their spectra. It uses the HEALPix subdivision scheme and is powered by the high-performance numerical package JAX, enabling its use on GPUs.

Note

In its beta version, spotter is mainly developed to estimate transmission spectra stellar contamination from stellar rotational light curves. Use at your own risk as the code is completely untested and its API subject to change.

Features

• Adjustable surface resolution - in beta
• Small-scale surface feature modeling (e.g., beyond limitations of starry) - in beta
• Modeling of active regions with unique angular dependence on brightness (e.g., limb-brightened faculae)
• GPU compatible - in beta
• Possibility to input any stellar spectra model

Installation

For now only locally with

pip install -e spotter

with spotter cloned using

git clone https://github.com/lgrcia/spotter
