Gravity-darkening Coefficients for the Space Mission JWST, Based on PHOENIX Spherical Models at High Resolution: NIRCam, NIRISS, and NIRSpec Passbands
Abstract
Abstract Space-based photometry has revealed the subtle effects of gravity darkening on the light curves of transiting exoplanets, allowing valuable new information on these objects to be retrieved. For some applications, these effects are parametrized in terms of the wavelength-dependent gravity-darkening (GD) coefficients, y ( λ ). To facilitate such studies, here we present theoretical calculations based on high-resolution PHOENIX models, providing GD coefficients for 11 passbands used with three different instruments onboard JWST.
