Twinkle calculates and plots the stellar spectral energy distribution (SED) using empirical photometric data and stellar model grids. The code was originally created to help calculate the excess infrared (IR) flux from a star; the presence of an IR excess indicates dust orbiting the star. This dust likely results from the grinding and collisions of asteroids, influenced by a larger planetary object—pointing to the potential for finding planets. Twinkle quickly calculates the temperature and location of the dust to first order by fitting the assumed blackbody or modified blackbody function to the broadband excess emission.
