Exoplanet Calculator 🪐

4.6 μs

This calculator uses host star and orbital parameters from the literature to self-consistently calculate derived values used for estimating the observed signal (ΔD) produced by its planet's atmosphere.

How parameters were calculated

1.5 μs

The calculator first checks if there are missing input parameters and then calls the appropriate function to calculate them for each study. The resulting derived parameters are then calculated from them.

Everything was done with a "star first" approach, meaning that all stellar parameters were determined first, and then the planet parameters were determined self-consistently from that. If conflicting parameters are given, the calculator will try to give priority to using direct observables to perform calculations and error otherwise.

For transparency, the inputs used for each calculation are shown in parenthesis next to each parameter.

These are the functions used to calculate each parameter based on the combination of inputs given. No if statements or default "None" keyword arguments needed thanks to Julia's multiple dispatch! For ease of reference, these functions also return a string of the inputs used.
