  "abstract": "<p>Giant planet evolution models play a crucial role in interpreting observations and constraining formation pathways. However, the simulations can be slow or prohibitively difficult.<br>\n<br>\nTo address this issue, we calculate a large suite of giant planet evolution models using a state-of-the-art planetary evolution code. Using these data, we create the python program <em>planetsynth</em> that generates synthetic coolingtracks by interpolation. Given the planetary mass, bulk &amp; atmospheric metallicity, and incident stellar irradiation, the program calculates how the planetary radius, luminosity, effective temperature, and surface gravity evolve with time.<br>\n<br>\nWe demonstrate the capabilities of our models by&nbsp;estimating the metallicities from mass-radius measurements and by showing how atmospheric measurements can further constrain the planetary bulk composition. We also estimate the mass and metallicity of the young giant planet 51 Eri b from its observed luminosity.<br>\n<br>\nSynthetic evolution tracks have many applications, and we suggest that they are valuable for both theoretical and observational investigations into the nature of giant planets.</p>",
