GRASS - GRanulation and Spectrum Simulator

Stable Dev Build Status

GRASS is a package designed to produce realistic time series of stellar spectra with realistic line-shape changes from solar-like granulation. GRASS v1.0.x is described in detail in Palumbo et al. (2022). The results of this paper can be reproduced using the showyourwork workflow from this repo.

Examples

Generating synthetic spectra with GRASS only takes a few lines of Julia:

```julia using GRASS

parameters for lines in the spectra

lines = [5434.5] # array of line centers in angstroms depths = [0.75] # continuum-normalized depth of lines resolution = 7e5 # spectral resolution of the output spectra spec = SpecParams(lines=lines, depths=depths, resolution=resolution)

specify number of epochs (default 15-second spacing)

disk = DiskParams(Nt=25)

synthesize the spectra

wavelengths, flux = synthesize_spectra(spec, disk) ```

Additional details and examples can be found in the documentation.
